The sampled signal xn obtained above is processed by the

Question

x(t) = cos(100πt) - 5sin(600πt) + 3cos(200πt)

(a) Determine the fundamental frequency of signal x(t)

(b) Determine the Nyquist sampling rate such that no aliasing occurs in the sampled signal.

(c) Assuming the sampling rate is 600 Hz, obtain the discrete time signal x[n] after the sampling.

(d) The sampled signal x[n] obtained above is processed by the ideal D-to-C converters with the sampling rate (600 Hz). Obtain the representation of the continuous signal.
