Question

n=20;

fp=300;

fq=200;

fs=1000;

fn=2*fp/fs;

window=blackman(n+1);

b=fir1(n,fn,'high',window);

[H W]=freqz(b,1,128);

subplot(2,1,1);

plot(W/pi,abs(H));

title('mag res of hpf');

ylabel('gain in db-------->');

xlabel('normalized frequency------>');

subplot(2,1,2);

plot(W/pi,angle(H));

title('phase res of hpf');

ylabel('angle-------->');

xlabel('normalized frequency------>');​
