9.2 For the discrete-time periodic signal x[n] (a) Determine its fundamental period No. (b) Suppose we sample the continuous-time signal x(t) = cos (?t) with a sampling period T = 0.7. Is the Nyquist sampling condi- tions satisfied? How does the sampled signal compare to x[n]? (c) Under what conditions would sampling a continuous-time signal x(t) = cos (?t) give a discrete-time sinusoid x[n] that resembles x(t)? Explain and give an example. = cos (0.7??),
.2 For the discrete-time periodic signal x[n]=cos(0.7?n), (a) Determine its fundamental period N0?. (b) Suppose we sample the continuous-time signal x(t)=cos(?t) with a sampling period Ts?=0.7. Is the Nyquist sampling conditions satisfied?How does the sampled signal compare to x[n] ? (c) Under what conditions would sampling a continuous-time signal x(t)=cos(?t) give a discrete-time sinusoid x[n] that resembles x(t) ? Explain and give an example.
