So basicalyi have to apply a 10th order (hamming window) band passfilter on a signal.I have designed the filter but unable to apply on signal
fs=300 hz,and fc1=10 and fc2 =15 . THe design code is following please tell me how to apply it on a signal
n=10;
fs=300;
dt=1/fs;
t=0:dt:1-dt;
fc1=10;
fc2=15;
wc1=fc1/(fs/2);
wc2=fc2/(fs/2);
b_p=fir1(n,[wc1 wc2],'bandpass',hamming(n+1));
[H,w] = freqz(b_p,1);
figure
plot(w/pi,20*log(abs(H)),'b')
PLEASE HELP!!!!!!

You need to continue the code by calling the filter() function. See further down in the help of fir1() for an example where they high pass filtered the signal.

Not sure what to expect, but if it gives that, then that's what you told it to give you. It will do just what you tell it to. Are they both space or time domain signals? I don't know why the x axes tick marks are different.
