What is the difference between a phase-shift oscillator with a high-pass frequency network and one with a low-pass frequency network? I've read that the HPF one has lower distortion but is that all?
Also, if you have three low-pass filters in series in the network I know that you should have an amplifier with a phase of -180o. Is this the same with high-pass filters in series? My assumption is yes because you will still have the phase offset from the filters which needs to be corrected to satisfy the Barkhausen criteria.
