You'll find a simple example of an analogue FIR filter in old PAL TV sets (PAL is the analogue colour TV system in use in much of Europe (the French of course had to be different) - it's NTSC in N America & Japan). The colour signal processing uses an analogue delay line (which used to be glass) in a simple two line vertical filter which reduces hue errors. Digital delays are much easier to make and use - so FIR filters are much more common (and can be much more complex) in the digital domain. -- Patrick Dixon www.at-tunes.co.uk ------------------------------------------------------------------------ Patrick Dixon's Profile: http://forums.slimdevices.com/member.php?userid=90 View this thread: http://forums.slimdevices.com/showthread.php?t=26685 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
