In terms of modern trends and fashions, I agree that minimum phase and slow roll offs come together, but if I remember what I learned in filter design class, not so much. For example any Butterworth filter is minimum phase, and all it takes is a fairly high order of Butterworth filter and a 20 KHz (-3) filter to provide a 100 dB stop band at the 44.1 KHz Nyquist frequency. There is a matter of practiality, except that minimum phase digital filters are completely possible. ------------------------------------------------------------------------ arnyk's Profile: http://forums.slimdevices.com/member.php?userid=64365 View this thread: http://forums.slimdevices.com/showthread.php?t=104094 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
