The received signal r(t) s(t) + n(t) in a communication system is passed through an ideal lowpass filter (LPF) with Bandwidth W and unity gain. The signal component s(t) has a power spectral density = Ss(f) Po 1+ (f/B)² Where B is the 3 dB bandwidth. The noise component n(t) has a power spectral density No/2 for all frequencies. Determine and plot the SNR using Matlab as a function of the ratio W/B. What is the filter bandwidth W that yields as a maximum SNR? Using Matlab,
