Hello everyone!
I am studying digital signal processing course and i want to make Fir low pass filter in matlab by using my owns filter's coefficients(not built in matlab commands).
I have determined the filter order from N=4/Normalizes of the transition width, which is 144.
where Fs(sampling frequency) is 7200Hz, fp (pass-band edge frequency) is 500Hz and fs(stop-band edge frequency) is 700Hz.
Now, i am stuck in (1)to create an ideal impulse response and then (2) apply Blackman window function on it to calculate my filter's coefficients.
i am facing problems in matlab commands to implement (1) and (2).
Can anyone help me?
