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.
