Consider the system shown in Figure 8.24. The noise is white with two-sided power spectral density 1/2 N₀. The power spectral density of the signal is

The parameter f₃ is the 3-dB bandwidth of the signal. The bandwidth of the ideal low pass filter is W. Determine the SNR of y(t). Plot the SNR as a function of W / f₃.
