[sci.electronics] Passive and active EQ's and filters for walkmans.

sorka@ucscb.UCSC.EDU (Alan Waterman) (07/16/90)

Does anyone know where I can find good source material that will help
me build small active(AAA*2 powered) or passive filters or EQ's.

I.E. one thing I want to build is a tiny 20 db bass boost in the 60 Hz
range, probably using CMOS.

Can anyone help me?????
