Consider a CT system shown below. The Bode plots of H(s) Magnitude (dB) Phase (deg) -5 -10 -15 -20 -25 -30 -35 40 & 2 45 -50 90 = Uk- u(t) 12.638 +12.63 8+1.579x10 Hold H(s) Bode Diagram of H are shown below. 10 Frequency (radis) a) Given this information, what would be a suitable choice of sampling period T in the sampled-data system shown below. Explain your answer in terms of the conditions described in the Sampling Theorem with impulse-train sampling. u(t) y(t) H(s) y(t) T Yk b) Using part a), give a formula for the frequencies which appears in the Fourier transform Y(e) of the sampled signal when u(t) = sin wyt, wo = 126 rad/sec.
