显示 更早的评论
I found function for one-third-octave filter:
Can someone help me and tell how it will look similar function for octave filter?

Do you have fdesign.octave in your installation?
You can design both octave and 1/3 octave filters with fdesign.octave

but fdesign.octave can handle both 1/3 and octave very easily.

Alexander, I don't see how using fdesign.octave with an input argument 1 (for octave band) vs. 3 (for 1/3 octave band) is harder than asking somebody to rewrite an entire function.
This is a 1/3 octave band design.
d1 = fdesign.octave(3,'Class 1','N,F0',6,10000,48000);
Hd1 = design(d1);
fvtool(Hd1);
This is an octave band design.
d2 = fdesign.octave(1,'Class 1','N,F0',6,1000,48000);
Hd2 = design(d2);
fvtool(Hd2);

Hi,
I'm using fdesign as Wayne suggest but the problem is that this function only reach to 20KHz and I need to be able to analyze also frequencies close to 50KHz. Anyone knows how to increase the bandwidth of fdesign or any other way of solving the problem?
All the best
