Kindly tellme why book has used magnitude squared..
The second figure is obtained by this matlab code
h770=[];
L=10;
fs=8000;
fb=770;
h770 = (2/L)*cos(2*pi*fb*(0:L-1)/fs);
subplot(2,1,1)
stem(h770) % Plotting with L=10
title('Bandpass Filter for L=10 for h770')
L=100;
h770 = (2/L)*cos(2*pi*fb*(0:L-1)/fs);
subplot(2,1,2)
stem(h770) % Plotting with L=100
title('Bandpass Filter for L=100 for h770')
Kindly tell me
What is each group
Are these co-efficients from fourier series
Thanks a lot
