The waveform at the input of a baseband system has signal power PT and white noise with single-sided power spectral density N0. The signal bandwidth is W. In order to pass the signal without significant distortion, we assume that the input waveform is band limited to a bandwidth B = 3W using a Butterworth filter with order n. Compute the SNR at the filter output for n = 1; 3; 5, and 10 as a function of PT /N0W. Also compute the SNR for the case in which n→∞. Discuss the results.
