Electrical Symbols — Analog and Digital Logic
Digital electronics or digital (electronic) circuits are electronics that handle digital signals – discrete bands of analog levels – rather than by continuous ranges (as used in analogue electronics). All levels within a band of values represent the same numeric value. Because of this discretization, relatively small changes to the analog signal levels due to manufacturing tolerance, signal attenuation or parasitic noise do not leave the discrete envelope, and as a result are ignored by signal state sensing circuitry.

How to Create an Electrical Diagram Using Analog and Digital Logic Library
- Open ConceptDraw DIAGRAM new document page.
- Select libraries from Electrical Engineering section.
-
There are a few different ways to place an object into your drawing:
- Click on an object and then click on the document, at the place you want the object to be inserted.
- Perform a drag-and-drop from the library to your document.
- Double click on an object’s icon in the library to place an object in the center of your document.
- Select the Smart Connector tool
. To connect elements using this tool, drag the connector from one connect dot to another.You can use Layers to place connections on different layers.
- Result: Circuit Diagram.

Electrical Symbols — Resistors →
A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. Resistors may be used to reduce current flow, and, at the same time, may act to lower voltage levels within circuits. In electronic circuits, resistors are used to limit current flow, to adjust signal levels, bias active elements, and terminate transmission lines among other uses. Fixed resistors have resistances that only change slightly with temperature, time or operating voltage. Variable resistors can be used to adjust circuit elements (such as a volume control or a lamp dimmer), or as sensing devices for heat, light, humidity, force, or chemical activity. 26 libraries of the Electrical Engineering Solution of ConceptDraw DIAGRAM make your electrical diagramming simple, efficient, and effective.

Electrical Symbols — Semiconductor Diodes →
In electronics, a diode is a two-terminal electronic component that conducts primarily in one direction (asymmetric conductance); it has low (ideally zero) resistance to the flow of current in one direction, and high (ideally infinite) resistance in the other. A semiconductor diode is a crystalline piece of semiconductor material with a p–n junction connected to two electrical terminals. Today, most diodes are made of silicon, but other semiconductors such as selenium or germanium are sometimes used. 26 libraries of the Electrical Engineering Solution of ConceptDraw DIAGRAM make your electrical diagramming simple, efficient, and effective.

Network VOIP. Computer and Network Examples →
Voice-over-Internet protocol (VoIP) is a protocol of the voice communications and multimedia sessions through the Internet or other packet-switched networks. VoIP systems use the data compression techniques, encapsulated in a data-packet stream over IP. They allows users to use regular telephone networks through any internet service provider and anywhere. VoIP is also called IP telephony, Internet telephony, Voice over broadband (VoBB). This example was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows the VoIP Network.

Electrical Symbols — Rotating Equipment →
Electrical rotating machines, such as motors and generators, are vital assets for any power plant or large industrial company. An electric motor is an electrical machine that converts electrical energy into mechanical energy. The reverse of this would be the conversion of mechanical energy into electrical energy and is done by an electric generator. In normal motoring mode, most electric motors operate through the interaction between an electric motor's magnetic field and winding currents to generate force within the motor. In certain applications, such as in the transportation industry with traction motors, electric motors can operate in both motoring and generating or braking modes to also produce electrical energy from mechanical energy. 26 libraries of the Electrical Engineering Solution of ConceptDraw DIAGRAM 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.

Network diagrams with ConceptDraw DIAGRAM →
Of course it is possible to keep network records in text documents, but it is very difficult to use them later. A more sound way to keep such documentation is to create a network diagram that might represent either logical network structure or physical. These diagrams are easy to understand and you will thank yourself later. There is a physical network diagram. It is a tool to represent, maintain and analysis of network equipment and interconnections. Network diagram depicts the actual network information in the attractive clear graphic form. One can learn here the LAN cable length, telecommunication type and carrying capacity. The diagram depicts servers, IP address and domain name as well. Also it shows location of hubs, switches, modems, routers, and other network equipment. The sets of special symbols and images delivered with ConceptDraw Network Diagrams solution are used to show network components. Symbols have a standard view. Therefore, various specialists can read the network diagram without any discrepancies.
