Butterworth

This function file is basically for Passive Butterworth Filter for Low pass as well as for High Pass. In input it takes the Pass Band Attenuation, Band Stop attenuation, Band Pass Frequency, band stop frequency, and Filter Type. For Low Pass Type is "0" and for High Pass Type is "1".It finally...

You can use 4 types of filters:- Butterworth- Chebyshev 1- Chebyshev 2- EllipticYou can use them as:- Lowpass- Highpass- Bandpass- StopbandShowing theirs features in frequency, phase and the z plane. After the desing phase you can apply the designed filter in real time to incoming audio signal... Platforms: Matlab

ButterParam - Fast parameters for a digital Butterworth filterThe calculation of filter parameters with BUTTER is expensive. Therefore ButterParam stores calculated parameters in a lookup-table to accelerate repeated calls with the same input.Example: x = rand(10000, 1); % test data [B, A] =... Platforms: Matlab
