Are there any DPDT switch that can take negative input?
i want to put a sinusoidal as input and use the output to go through a difference amplifier to create a rectifier.
does it work the same if i put a DC offset so i only get positive sinusoidal input to DPDT, and then use the output to go through a difference amplifier? (maybe i need to subtract DC offset to get the equivalent as without no offset?)
