Question: The input/output relation of a non-linear system is y(t) = x 2 (t), where x(t) is the input and y(t) is the output. (a) The

The input/output relation of a non-linear system is y(t) = x2(t), where x(t) is the input and y(t) is the output.

(a) The signal x(t) is band-limited with a maximum frequency ΩM = 2000π(rad/sec), determine if y(t) is also band-limited and if so what is its maximum frequency ­max.

(b) Suppose that the signal y(t) is low-pass filtered. The magnitude of the low-pass filter is unity and the cut-off frequency is Ωc = 5000π(rad/sec), determine the value of the sampling period Ts according to the given information.

(c) Is there a different value for Ts that would satisfy the Nyquist sampling rate condition for sampling both x(t) and y(t) and that is larger than the one obtained above? Explain.
