In an analog communication system, demodulation gain is defined as the ratio of the SNR at the output of the demodulator to the SNR at the output of the noise- limiting filter at the receiver front end. Find expressions for the demodulation gain in each of the following cases: 1. DSB. 2. SSB. 3. Conventional AM with a modulation index of a. What is the largest possible demodulation gain in this case? 4. FM with modulation index Bf.

Respuesta :

A signal-to-noise ratio, sometimes written S/N or SNR, is a measurement of the strength of the intended signal in relation to background noise in analog and digital communications (undesired signal).

By comparing the two levels and returning a ratio, a predefined formula can be used to calculate S/N. This ratio reveals if the desired signal is being impacted by the noise level. Typically, the ratio is given as a single decibel number (dB). The ratio might be either a positive or negative value, or it can be zero. The signal level is greater than the noise level when the signal-to-noise ratio is greater than 0 dB. The signal quality improves as the ratio rises.
