A more detailed RC high pass filter calculator. This is the filter on the output of ProtoDAC.
The Bode plot of amplitude and phase response. In audiophile equipment, you want phase shifts outside the audio band as much as possible.
Why you shouldn't use a 1uF cap at 10kOhm impedence. Corner frequency is 15.915Hz, but phase shift at 20Hz is 38.51 degrees.
