Noise and Frequency Modulation: Noise and Frequency Modulation is much more immune to noise than amplitude modulation and is significantly more immune than phase modulation. In order to establish the…
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…
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…
Single Sideband: A brief, if not oversimplified, explanation of Single Sideband will help in understanding the transmission process. To begin, we must review some basic transmission processes. The physical length…
Amplitude Modulation Articles: 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…
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 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…
