Phase Discriminator: This Phase Discriminator is also known as the center-tuned discriminator or the Foster-Seeley discriminator, after its inventors. It is possible to obtain the same S-shaped response curve from…
Color Television Receiver Block Diagram: Figure 17-25 shows the block diagram of a Color Television Receiver Block Diagram, but for simplicity the circuits shown in Figure 17-23 are omitted. Interconnection…
Moving Target Indicator Radar Block Diagram: Basically, the Moving Target Indicator Radar Block Diagram compares a set of received echoes with those received during the previous sweep. Those echoes whose…
Pulsed Radar System Block Diagram: A very Pulsed Radar System Block Diagram set was shown in Figure 16-1. A more detailed block diagram will now be given, and it will…
Telegraphy in Electronic Communications: Telegraphy in Electronic Communications that employs typewriter like machines operating at a maximum speed of about 60 words per minute (wpm) to send written messages from…
Radio Receivers Articles: Tuned Radio Frequency Receiver: The Tuned Radio Frequency Receiver is a simple “logical” receiver. A person with just a little knowledge of communications would probably expect all…
Receiver Types: There are Two Receiver Types namely, Pilot Carrier Receiver and a Suppressed Carrier Receiver; the suppressed carrier receiver incorporates a frequency synthesizer for extra stability and also is…
Ratio Detector Circuit: In the Foster-Seeley discriminator, changes in the magnitude of the input signal will give rise to amplitude changes in the resulting output voltage. This makes prior limiting…
