5. The transfer function of the filter shown in Fig. 4 is given by H(f) = rect(f/28.), The signal s(t) = 5 cos(27 ft+x/4) is applied to this filter, along with white noise W(t) as shown in Fig. 3. The frequency of the signal, f. = 500 Hz. The power spectral density of the white noise is S, (f)= K = 1x10 Watt/Hz. Find the output signal-to-noise ratio (SNR) when (a) f. = 800Hz. (b) f. = 200Hz. s(t) s(t)+w(t) + output H(f) White noise W(t) Fig. 4
