solve only one its ok!

((( using matlab )))

>>> the previous code is :

fs=100;

b=3;

>> fa=10;

>> x=linspace(0,t,n);

y=sin(2*pi*fa*x);

>> yq=round(y*2^(b-1))/2^(b-1);

>> plot(x,y)

After generating the continuous analog (CA) signal, add to the previous program) the script to generate the discrete analog (DA) signal Hint: The difference beytween the DA & CA signals is the samping rate, where: CA sampling rate >> DA sampling rate >>: much greater than) Requirements 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.
