carlo.cianferotti 2 posts Popping In	13-11-2009 18:23 Dear everybody, I remember an old project concerning an AC power meter, it was made using a bunch of bipolar transistor wired as a 4-quadrant analog multiplier and a moving coil uA-meter. I found it pretty clever for measuring true RMS power with very little effort. It sported a few switchable current and voltage ranges. It was on an old issue -I have all of them from 1989 to 2003- probably in one of those 100 circuits collection. Could anybody help me to find which issue belongs?

If I will get any knowledge about this than I will definitely reply your post! Thanks!
