Question
Problem 2 [15 points] For the given signals
1. r(t) = 4 sin(20πt)
2. r₂(t) 4 sin(80nt)
3. T3(t) = -4 sin(40πt)
Answer the following questions
a. [6 points] Using the MATLAB command stem to plot the signals formed by sampling the
above three functions over the interval 0 < t <1 with sampling rate of 30 Hz.
b. [6 points] Determine the Nyquist sampling rate for each signal.
c. [3 points] What do you observe?
