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…
Squelch Circuit: Squelch (muting):Â When no carrier is present at the input, i.e., in the absence of transmissions on a given channel or between stations, a sensitive receiver will produce a…
Theory of Frequency Modulation and Phase Modulation: Frequency Modulation and Phase Modulation is a system in which the amplitude of the modulated carrier is kept constant, while its frequency and…
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…
Sensors and Transducers: The definition of Sensors and Transducers are follows, The input quantity for most instrumentation systems is nonelectrical. In order to use electrical methods and techniques for measurement, the…
8096 Microprocessor Functional Units: Table 13.2 shows the list of major I/O functions provided by various 8096 Microprocessor Functional Units. Timers: The 8096 Microprocessor Functional Units has two 16 bit…
Serial Communication Interface in Microprocessor: The Serial Communication Interface in Microprocessor is full duplex, meaning it can transmit and receive simultaneously. It is also receive-buffered, meaning it can commence reception…
Symmetrical Components Articles: Symmetrical Component Transformation: Symmetrical Component Transformation is given by a set of three balanced voltages (phasors) Va,Vb,Vc is characterized by equal magnitudes and interphase differences of 120°.…
