Unfortunately, I don't think this is correct... The voltage across the top resistor is -9.6VDC... The voltage across the bottom resistor I would think is 5.8VDC, however, the original circuit was calculated using 13VAC across the bottom resistors... I would say this calculation was...

Ok. There should be an attachment included now. Basically, I'm trying to work backwards from some other peoples work. This is a summing circuit. V0 goes to an op-amp, but for this case the output voltage is zero. In these guys work I'm using, they convert the ac voltage off of a pot at a known...

Thanks. I've seen that equation, but from what I can tell, that is really just the average DC voltage. \int_0^{\pi}sin(t)*\sqrt{2}=\frac{\sqrt(2)}{\pi}VAC The problem with this is the signal is being subtracted from a -13VAC (180 deg phase shift) signal. The calculations other people used...

Hi, I have a circuit with a pot connected to an 26VAC signal through a diode and to ground... i.e. there is a half wave rectified signal across the pot. I'm then measuring the voltage off the wiper. I'm looking through some peoples work, and they write the max output voltage is...
