[Scilab-users] Plotting properties of digital audio filters

Hi Rafael,

Thank you for your reply. I have tried unwrapping the phase for the 24dB/oct
low pass filter at 1kHz with scilab's unwrap() function. Plots included
below; I scaled the frequency axis linearily to better show what's going on.

Kind regards,

Frederik
