An Accuracy Comparison of the Digital Filter Poles-Zeros Analysis
MetadataShow full item record
In the paper, a comparison of MATLAB and CIA procedures for computing the poles and zeros of digital filters is performed. The accuracy of both tools is tested using finite impulse response filters of a higher order - the first was designed by "remez" algorithm and the second came from the area of psychoacoustics.
