Phase Shift Independent of Frequency: Circuit Solutions

[GlynnHeeswijk]

Hi

Is anyone aware of a circuit that could provide a phase shift independent of frequency?
I have thought of doing it digitally but the number of components needed are ridicules.

Thank you

a delay line?

What's your purpose?

How much phase shift? Over what frequency range?

...and do you mean a constant phase shift in terms of number of micro/nano seconds, or a constant phase shift in terms of % of period?

A standard audio treble attenuator based on an R C circuit produces a phase shift that is dependent on frequency: 1 radian per neper, or 6.6 degrees per dB. This distorts the sound quality of the audio. How can we eliminate the phase shift?
