Hi all I have 2 DC voltage inputs, Va and Vb. Va varies from 0V to 10V, while Vb has output of + or - 1V. I want to change the sign of Va depending on whether Vb is positive or negative. All this has to be done in analog, not dsp. Current through the circuit is 1A max. I've thought of using a Gilbert
2Q multiplier, but I was wondering if there was another way. Thanks Sid- posted
