Re: the a102 diode filter./sallen-key

2002-06-05 by code_pig

Duff,

2 pole filtering has a 12dB per octave cutoff.  Also, I think you'll 
find that when one uses a LPF and a HPF together, what is created is 
a notch filter (see the A121 documentation for a graphic explanation).

Hope that helps a bit.

Regards,
Kevin
