Question 1

Consider the signal

x[n] = sin(ω₁n) + ksin(ω₂n),

where k is a real valued constant.

a) Write a program that will

1. Plot x[n].
2. Compute the N point DFT X[k]. (Yes, you may use FFT routines.)
3. Plot the magnitude of X[k].

Turn in a print out of your code.

b) Run your program and generate outputs for the cases shown below.
