NettetCrossover is at -6 dB points and the drivers are in phase so there is no tilt in the polar response. The filter slopes should be steeper though to make the crossover more … NettetLinked files: wsfir.h. notes ¶ This code generates FIR coefficients for lowpass, highpass, bandpass, and bandstop filters by windowing a sinc function. The purpose of this code is to show how windowed sinc filter coefficients are generated. Also shown is how highpass, bandpass, and bandstop filters can be made from lowpass filters.

This filter type was originally described in Active Crossover Networks for Noncoincident Drivers in the Journal of the Audio Engineering Society. It is also known as a Butterworth squared filter.
