Thread: Audio Ideas?
face BY : Alok Dubey email (remove spam text)

if u include the diode in the opamps f/b u have a log amp there itself...
might as well use an offset DC on it to make it fn as a log amp and simply
give this o/p to a A/D convertor.. and some nice math to compute the o/p in
again ur diode should be a nice one.. and some temp compensation will be
this is a std log amp ckt Vo/p =ln (Vi/p)=2.303log(Vi/p)
have fun and let me knw what u up to..
