Direct Synthesizer Block Diagram: A Direct Synthesizer Block Diagram is a piece of apparatus in which multiples and submultiples of a single crystal oscillator frequency are combined by addition and/or…
Automatic Frequency Control Block Diagram: Automatic frequency control: As previously we see, the heart of an AFC circuit is a frequency-sensitive device, such as the phase discriminator, which produces a…
Delayed Automatic Gain Control: Delayed Automatic Gain Control: Simple AGC is clearly an improvement on no AGC at all, in that the gain of the receiver is reduced for strong…
Working Principle of Automatic Gain Control: Working Principle of Automatic Gain Control is a system by means of which the overall gain of a radio receiver is varied automatically with…
Simple Diode Detector: Operation of diode detector: The Simple Diode Detector is by far the most common device used for AM demodulation (or detection), and its operation will now be…
Extensions of Single Sideband Amplitude Modulation: The Extensions of Single Sideband Amplitude Modulation is namely, Forms of Amplitude Modulation: This section on amplitude modulation defines, describes and lists the main applications…
Methods of Suppressing Unwanted Sidebands: As stated earlier, the three practical methods of SSB generation all use the balanced modulator to suppress the carrier, but each uses a different method…
Define Suppression of Carrier: Three main systems are employed for the generation of SSB; the filter method, the phase cancellation method and the "third method." They differ from one another…
