RE: Phase Shift

I wasn't aware that such a situation could occur within the passband from a first order cut-off filter. Can't argue with the sim results though. Having said that, the phase shift at 10 KHz is only 2 deg which is probably less than what is imparted to the signal by the OPT at that frequency. I guess the effect could be cumulative leading to distortion and higher order harmonics at a range where the ear is sensitive.

If you don't mind, could you please post a sim with a 1 uF or 1.5 uF capacitor? Just curious to see the difference.
