1. Generate & plot both the CA & the DA signals in one graph. Set the plot of the DA signal to display samples as red 'o'. Also, you should get the sampling interval & number of samples on the Command window. 2. Run with DA sampling rate:-100 Hz. a. Number of samples? b. Sample interval (At)? 3. Run with DA sampling rate:- 50 Hz. a. Number of samples? b. Sample interval (At)? 4. Run with DA sampling rate:- 10 Hz. a. Number of samples? b. Sample interval (At)? sin(w*t) sin(w*t) sin(w*t) Amplitude Amplitude Amplitude 0 0 0 0 0 0 -1- 0.25 0.5 0.5 0.25 Time (sec) 0.25 Time (sec) Time (sec) fs=100 Hz (100 samples/sec) fs=50 Hz (50 sample/sec) fs=10 Hz = 10 samples/sec 1.
