Question

1) Consider the continuous-time signal

x1(t) = sin(4πt)

a) What is the Nyquist rate for this

signal?

Suppose that we sample x1(t) at the rate fs = 50 Hz to generate the discrete-time signal x1[n]. Assume that one of the samples is at t = 0.

b) Determine the discrete-time signal x1[n].

c) Suppose that we sample the continuous-time signal
