MATLAB exercise for HW2 (please submit final plots)
Consider x(t) = sinc(100*t)*cos(2*pi*200*t)
1. Plot x(t), for -2 <= t <= 2 (use ts = .001 sec), and plot X(f) for -500 <= f <= 500 (use df = 0.5 Hz).
2. Choosing fo = 200Hz (carrier frequency), find the lowpass equivalent, x_l(t), of x(t) and plot its magnitude spectru. Plot the in-phase and quadrature components and the envelope of x_l(t)
3. Repeat part 2 assuming fo = 100 Hz.
Hint: Go to the homework link provided in the MATLAB folder and use the following m-files from Chap2: Loweq, quadcomp, env_phas, fftseq,
