uh, I'm afraid I don't really understand.then You were simply measuring the wrong Node for your Scope,s "Circuit-Input" display-channel.
Yes. but I'd still prefer the signal to be not inverted :^)The inversion of the phase is inaudible to the ear, as long as the same inversion is applied to both channels in a stereo system.
Woah. Thanks for going through that effort! Yes, I think this is what I had in mind. The phase is just like the input. Though I don't understand why it needs another opamp for that? My thinking was that an inverting amp before U2 should suffice to bring the singnal back to its original phase.hi d123,
Is this the non-inverting version you are requesting?
Nice catch!Your inversion problem arises because you have attached the Vin net-node label at two places: to V4 and to R1, thus effectively shorting out U1. Detach it from R1.
"Prefer" is generally not a valid engineering reason to make a circuit more complex.Yes. but I'd still prefer the signal to be not inverted :^)
