Please note that the op-amp is lm386 and the filters are passive RC filters.So the basic question is to get the true voltage analog reading for each band, should i shift the signal upwards or rectify it?
and if he already shifted it all upwards why did he use the rectifier at the end?
should i use another op-amp
