Fundamentals of Electromagnetic Waves: Fundamentals of Electromagnetic Waves are energy propagated through free space at the velocity of light, which is approximately 300 meters per microsecond. As the object travelled downward,…
Choke Balun: A Choke Balun, or balance-to-unbalance transformer, is a circuit element used to connect a balanced line to an unbalanced line or antenna. Or, as is perhaps a little…
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…
