Communication Receiver Block Diagram: A Communication Receiver Block Diagram is one whose main function is the reception of signals used for communications rather than for entertainment. It is a radio…
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…
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…
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…
External Noise in Communication System: The various forms of External Noise in Communication System created outside the receiver are namely 1. Atmospheric Noise, 2. Extraterrestrial Noise, Solar noise Cosmic noise…
