What is the best software to do filter. I need create an 8th order low pass butterworth filter.
Also from what I remember from by signal processing class (which was a long time ago) that filtering causes a time delay and phase shift. What is the best way of eliminating it or reduce the affects from it.
Thanks in advance.
