1) Consider the continuous-time signal
x1(t) = sin(4πt)
a) What is the Nyquist rate for this
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
