vrf Lowpass filter

Question asked by VRFuser on Feb 8, 2002
Majed,

All you need for a simple filter is to send the data through the fft()
function, multiply by the filter transfer function, and then send the result
through the ifft() function. The filter function can be anything you want,
even if it is not strictly "realizable", so you could use just a simple
brick wall that is 1 up to 300 Hz and 0 beyond 300 Hz.

Bill Ossmann
