WebNoise is a form of amplitude variations in the transmitted signal due to several factors such as the atmosphere, industries, etc. This noise can be reduced by increasing the deviation of the frequency of the signal. Web© KKL 3 We must find a way to quantify (=to measure) the performance of a modulation scheme. We use the signal-to-noise ratio (SNR) at the output of the receiver:
