hi, im little new using matlab and these is my first post ^^
I have use the function impz to do it and i need to compare with the
response using filter, but im no relly sure how to do it.
with impz
N = 40;
num = [0.9 -0.45 0.35 0.002];
den = [1 0.71 -0.46 -0.62];
y = impz(num,den,N);
what i tryed
N = 0:40;
num = [0.9 -0.45 0.35 0.002];
den = [1 0.71 -0.46 -0.62];
y = filter(num,den,N);
no really sure is these is rigth
