Electrical Symbols — Delay Elements

Variable delay elements are often used to manipulate the rising or falling edges of the clock or any other signal in integrated circuits. Delay elements are also used in delay locked loops and in defining a time reference for the movement of data within those systems.

26 libraries of the Electrical Engineering Solution of ConceptDraw PRO make your electrical diagramming simple, efficient, and effective. You can simply and quickly drop the ready-to-use objects from libraries into your document to create the electrical diagram.
The design elements library "Cable TV" contains 64 symbols of CATV network equipment.
"Cable television is a system of distributing television programs to subscribers via radio frequency (RF) signals transmitted through coaxial cables or light pulses through fiber-optic cables. This contrasts with traditional broadcast television (terrestrial television) in which the television signal is transmitted over the air by radio waves and received by a television antenna attached to the television. FM radio programming, high-speed Internet, telephone service, and similar non-television services may also be provided through these cables.
The abbreviation CATV is often used for cable television." [Cable television. Wikipedia]
Use the shapes library "Cable TV" to draw CATV system design floor plans, network topology diagrams, wiring diagrams and cabling layout schemes using the ConceptDraw PRO diagramming and vector drawing software.
The vector stencils library "Cable TV" is included in the Electric and Telecom Plans solution from the Building Plans area of ConceptDraw Solution Park.

"Audio connectors and video connectors are electrical connectors (or optical connectors) for carrying audio signal and video signal, of either analog or digital format. Analog A/ V connectors often use shielded cables to inhibit radio frequency interference (RFI) and noise." [Audio and video connector. Wikipedia]
"The existence of many different audio and video standards necessitates the definition of hardware interfaces, which define the physical characteristics of the connections between electrical equipment. This includes the types and numbers of wires required along with the strength and frequency of the signal. It also includes the physical design of the plugs and sockets.
An interface may define a connector that is used only by that interface (e.g., DVI) or may define a connector that is also used by another interface; for example, RCA connectors are defined both by the composite video and component video interfaces.
Audio connectors and video connectors are electrical connectors (or optical connectors) for carrying audio signal and video signal, of either analog or digital format. Analog A/ V connectors often use shielded cables to inhibit radio frequency interference (RFI) and noise.
Since both analog and digital signals are used with some styles of connectors, knowledge of the interface used is necessary for a successful transfer of signals. Some interface types use only a distinctive connector or family of connectors, to ensure compatibility. Especially with analog interfaces, physically interchangeable connectors may not carry compatible signals.
Some of these connectors, and other types of connectors, are also used at radio frequency (RF) to connect a radio or television receiver to an antenna or to a cable system..." [Audio and video interfaces and connectors. Wikipedia]

The vector stencils library "Transistors" contains 30 symbols of transistors drawing electronic schematics and circuit diagrams.
"A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power. It is composed of semiconductor material with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor's terminals changes the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Today, some transistors are packaged individually, but many more are found embedded in integrated circuits.
The transistor is the fundamental building block of modern electronic devices, and is ubiquitous in modern electronic systems. ...
Transistors are categorized by:
(1) Semiconductor material...: the metalloids germanium ... and silicon ... in amorphous, polycrystalline and monocrystalline form; the compounds gallium arsenide ... and silicon carbide ..., the alloy silicon-germanium ..., the allotrope of carbon graphene ...
(2) Structure: BJT, JFET, IGFET (MOSFET), insulated-gate bipolar transistor, "other types"
(3) Electrical polarity (positive and negative): n–p–n, p–n–p (BJTs); n-channel, p-channel (FETs)
(4) Maximum power rating: low, medium, high
(5) Maximum operating frequency: low, medium, high, radio (RF), microwave frequency...
(6) Application: switch, general purpose, audio, high voltage, super-beta, matched pair
(7) Physical packaging: through-hole metal, through-hole plastic, surface mount, ball grid array, power modules...
(8) Amplification factor..." [Transistor. Wikipedia]

The vector stencils library "VHF UHF SHF" contains 52 symbols for VHF, UHF, and SHF circuit design, including capacitance measurers, nonreciprocal devices, modulators, phase shifters, field polarization devices, and filters.
"Very high frequency (VHF) is the ITU-designated range of radio frequency electromagnetic waves from 30 MHz to 300 MHz, with corresponding wavelengths of one to ten meters. Frequencies immediately below VHF are denoted high frequency (HF), and the next higher frequencies are known as ultra high frequency (UHF).
Common uses for VHF are FM radio broadcasting, television broadcasting, land mobile stations (emergency, business, private use and military), long range data communication up to several tens of kilometres with radio modems, amateur radio, and marine communications. Air traffic control communications and air navigation systems (e.g. VOR, DME & ILS) work at distances of 100 kilometres or more to aircraft at cruising altitude.
VHF was previously used for analog television stations in the US." [Very high frequency. Wikipedia]
"Ultra-high frequency (UHF) designates the ITU radio frequency range of electromagnetic waves between 300 MHz and 3 GHz (3,000 MHz), also known as the decimetre band or decimetre wave as the wavelengths range from one to ten decimetres; that is 1 decimetre to 1 metre. Radio waves with frequencies above the UHF band fall into the SHF (super-high frequency) or microwave frequency range. Lower frequency signals fall into the VHF (very high frequency) or lower bands. UHF radio waves propagate mainly by line of sight; they are blocked by hills and large buildings although the transmission through building walls is high enough for indoor reception. They are used for television broadcasting (digital and analogue), cordless phones, walkie-talkies, satellite communication, and numerous other applications.
The IEEE defines the UHF radar band as frequencies between 300 MHz and 1 GHz. Two other IEEE radar band overlap the ITU UHF band: the L band between 1 and 2 GHz and the S band between 2 and 4 GHz." [Ultra high frequency. Wikipedia]
"Super high frequency (or SHF) is the ITU designation for radio frequencies (RF) in the range of 3 GHz and 30 GHz. This band of frequencies is also known as the centimetre band or centimetre wave as the wavelengths range from ten to one centimetres. These frequencies fall within the microwave band, so radio waves with these frequencies are called microwaves. The small wavelength of microwaves allows them to be directed in narrow beams by aperture antennas such as parabolic dishes, so they are used for point-to-point communication and data links, and for radar. This frequency range is used for most radar transmitters, microwave ovens, wireless LANs, cell phones, satellite communication, microwave radio relay links, and numerous short range terrestrial data links. The commencing wireless USB technology will be using approximately 1/ 3 of this spectrum.
Frequencies in the SHF range are often referred to by their IEEE radar band designations: S, C, X, Ku, K, or Ka band, or by similar NATO or EU designations." [Super high frequency. Wikipedia]

The vector stencils library "Telecommunication networks" contains 32 clipart images of telecommunication network devices and equipment for drawing telecom network diagrams.
"A telecommunications network is a collection of terminal nodes, links and any intermediate nodes which are connected so as to enable telecommunication between the terminals.
The transmission links connect the nodes together. The nodes use circuit switching, message switching or packet switching to pass the signal through the correct links and nodes to reach the correct destination terminal.
Each terminal in the network usually has a unique address so messages or connections can be routed to the correct recipients. The collection of addresses in the network is called the address space." [Telecommunications network. Wikipedia]

The vector stencils library "Cisco network topology" contains 89 symbols of Cisco network devices and design elements for drawing computer network topology diagrams.
"There are two basic categories of network topologies:
(1) Physical topologies,
(2) Logical topologies.
The shape of the cabling layout used to link devices is called the physical topology of the network. This refers to the layout of cabling, the locations of nodes, and the interconnections between the nodes and the cabling. The physical topology of a network is determined by the capabilities of the network access devices and media, the level of control or fault tolerance desired, and the cost associated with cabling or telecommunications circuits.
The logical topology in contrast, is the way that the signals act on the network media, or the way that the data passes through the network from one device to the next without regard to the physical interconnection of the devices." [Network topology. Wikipedia]
