Sample 2: Composite Image Filter Block Diagram

Electronic Block Diagram sample: This sample shows a composite image filter. It is a kind of electronic filter including several image filter sections, in common of two or more types, organized into a ladder network. The number of filter sections is determined by the amount of stopband rejection required. The image impedances always match in a composite image filter. The imaging method of filter design is used to calculate the properties of these filter sections.

Sample 4: LNB Block Diagram

Electronic Block Diagram sample: This sample shows a low-noise block downconverter (LNB). It is a receiving device that combines a low-noise amplifier, local oscillator, frequency mixer, and intermediate frequency amplifier. LNB is installed on the satellite dishes to receive the signals from the satellite. This device converts the radio waves collected by the dish into a signal and amplifies it. Next, NLB down-converts this signal to a lower block of intermediate frequencies.

Sample 5: Multi Mode Receiver Block Diagram

Electronic Block Diagram sample: This sample shows a multi mode receiver also known as amateur radio. It is a piece of equipment using the radio frequency spectrum to exchange messages, send, receive, or relay radio communications between radio amateurs. Amateur radio is a popular hobby, radio sport, or self-training. It is used in experiments, explorations, emergency communication, and for more personal and non-commercial purposes.

Sample 6: Phase Locked Loop

Electronic Block Diagram sample: This sample shows a simple analog phase-locked loop (PLL) circuit. It works like a narrow band filter and generates an output signal with a phase related to the phase of the input signal. PLL is a circuit commonly used in radio and telecommunications systems, computers and other electronics. It is used to demodulate the signal, generate a stable frequency, and help recover the signal from a noisy communication channel.

Sample 9: Series and Parallel Crossover Topologies

Electronic Block Diagram sample: This sample shows the series and parallel crossover topologies. Audio crossovers are used in loudspeakers and power amplifiers for audio and musical instruments and consumer electronics. These are electronic filter circuits designed to split an audio signal into two or more frequency bands, which are then sent to loudspeaker drivers or other devices with crossovers installed.

Sample 10: Sigma Delta ADC

Electronic Block Diagram sample: This sample shows a rsigma-delta analog-to-digital converter (ADC). It is a system that converts an analog signal into a digital one. Light entering a digital camera or sound picked up by a microphone are examples of analog signals. The main components of an ADC are a sigma-delta modulator and a digital filter.

Sample 11: Simple TRF Receiver Block Diagram

Electronic Block Diagram sample: This sample shows a tuned radio frequency (TRF) receiver. TRF receiver was invented in the 1920s. It is a type of radio receiver amplification circuit consisting of one or more tuned radio frequency (RF) amplifiers. The tuned circuit, acting as a band pass filter, precedes the RF amplifier. Next comes the demodulator or detector, designed to extract the audio signal from the radio carrier wave. The audio amplifier completes the circuit.

Sample 12: Theremin Block Diagram

Electronic Block Diagram sample: This sample is a theremin circuit. Also known as the etherophone, thereminvox, the reminophone, the theremin is an electronic musical instrument invented by Leon Theremin in 1928. This instrument is controlled by the theremin without physical contact. Theremin consists of two metal antennas. The thereminist is in front of the instrument and controls it by moving its hands near these antennas.

Sample 13: TRF Receiver Block Diagram

Electronic Block Diagram sample: This sample shows a tuned radio frequency (TRF) receiver. It consists of one or more tuned RF amplifier stages, a detector, and one or more audio amplifiers. A tuned RF amplifier amplifies the signal to a level required to run the detector, which extracts the audio signal from it through a rectification. In turn, the audio amplifier increases the power of the audio signal. Each tuned RF stage includes an amplifying device, a triode vacuum tube, and a tuned circuit filtering the signal.

Sample 14: UML Use Case Diagram Template — System of Goods Selling via Catalogues

Electronic Block Diagram sample: This sample shows a reflex direct-amplifying radio receiver. It is a type of radio receiver with an amplifier implementing two functions at once. It is used both to amplify the high-frequency radio signal (RF) and low-frequency audio signal (AF). The radio signal enters from the tuned circuit and antenna and passes through an amplifier to the demodulator or detector.
