To the left is a schematic of a full-wave rectifier. Again, ... (Scope GND to DC-), you should see a true rectified full wave waveform (120Hz) of the original 60Hz.

The incoming AC waveform (a sinewave is shown) is scaled by R1 and routed by A1 to the Q1/Q2 complementary pair, with the positive half-cycles going to Q1 and the negative to Q2. Q1’s share of the ...

Full-Wave Rectifier: An electronic circuit that converts the entire AC waveform into a unidirectional output, utilising both halves of the input cycle. Precision Rectification: ...

High-Speed Full-Wave Rectifier Requires No Diodes, Few Parts June 7, 2007 Systems requiring power conversion and level detection employ full-wave rectification, traditionally provided by a diode ...

So far, I had a promising idea for a half-wave rectifier that didn’t need any diodes or analog switches. Super. But I wanted full-wave rectification. Nothing for it but to add a second op amp, IC1b.
