Is there a simple way to shift the audio signal (phase) by 90, 180, and 270 degrees in the ADAU1701? I think that a simple inverter block will give me 180, but how do I hit 90 and 270?
Thanks for any suggestions,
The invert block will give you a 180 degree phase shift in your signal. Unfortunately, I don't think that there's an easy way to simply shift a signal by an arbitrary amount (such as 90 or 270 degrees), since the shift in time will be variable across the range of frequencies.
