Generation of Frequency Modulation: The Generation of Frequency Modulation system is a variable output frequency, with the variation proportional to the instantaneous amplitude of the modulating voltage. The subsidiary requirements…
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…
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…
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…
Amplitude Modulation Theory: In Amplitude Modulation Theory, the amplitude of a carrier signal is varied by the modulating voltage, whose frequency is invariably lower than that of the carrier. In…
Noise Temperature in Communication System: The concept of noise figure, although frequently used, is not always the most convenient measure of noise, particularly in dealing with UHF and microwave low-noise…
Noise Figure in Communication System: The Noise Figure in Communication System are namely, 1.Signal to Noise Ratio: The calculation of the equivalent noise resistance of an amplifier, receiver or device may…
Internal Noise in Communication System: Under the heading of Internal Noise in Communication System, we discuss noise created by any of the active or passive devices found in receivers. Such…
