Question
Plot the frequency responses using the MATLAB function freqz() for each of z-transfer functions.MATLAB>>freqz(bLP,1,512,8000); % sampling rate=8000 Hz
Label and print your graph.
Perform similar operations for FIR systems with coefficients: bBP and label and print your plots.
iii. Generate the sum of sinusoids for duration of 1 second:
x(t)=5 cos?(1000?t)+5 cos?(2400?t+0.25?)+5cos?(3600?t+0.5?) using a sampling rate of 8 kHz.
Hint: MATLAB>> t=0:(1/8000):1.0;
>> x=5*cos(1000*pi*t)+5*cos(2400*pi*t+0.25*pi)...
+5*cos(3600*pi*t+0.5*pi);
