Good evening,
I’m trying to find out which loww-pass type is applied when I choose roll-off 12 db. I see in the Nyquist plug-in it’s calling lowpass2 function, but can’t find the function script anywhere. Does anyone have any idea what filter it is? Looks like FIR, but I must confirm.
I will appreciate your support
“Nyquist’s built-in filters have frequency dependent phase shift. This is because they are IIR Butterworth filters, and frequency dependent phase shift is a characteristic of IIR filters.”

This is what the Nyquist manual says about lowpass2: lowpass2
Thank you so much, this is exactly what I was looking for~
