i need to rework a LM358 opamp based recision rectifier from a split
+/- 5v supply to a single ended supply. i biased the non-invert input to half supply volts using a voltage divider. the feed is the secondary of a CT. for symmetry i would think that i still connect the secondary of the CT to the same points in the circuit (do i need to capicitive couple?i didn't b4). Also I would think thet the output ma meter would be placed between o/p pin and ground...or should this also be between the output and the noninvert pin bias voltage. many thx.- posted
