Could SigmaStudio implement phase shift in a certain frequency piont?
At ADAU1761 platform, I have implement a phase shift follow the below link, it was amazon method to adjust output phase degree.
https://ez.analog.com/message/153588#153588
But It was similar with phase shift theory base on delay, the whole frequency signal in the delay chain change to a fixed degree, compare to reference signal.
In my application, I want to reverse like 100Hz piont phase from -180' to +180', just like below firgure. Actually, it was a feature from TAS5709 named "phase shift". Recently I need change to ADAU1761 platfrom, the "phase shift" was a necessary, but I can not found the "phase shift" soft module in Sigmastudio. Is there any certain module or method to implement the feature in Sigmastudio? TKS!

HI Felix:
What you are looking for is a 2nd order All Pass Filter. It's available on the standard library on the 1761.
The confusion is on the difference between names used.
Hope this helps.
Please try to use it and verify the phase shift using a stimuli and probe

It is perfect, thanks very much, Miguel.
I have simulat this, got expectative curve, it just different display mode from TAS5709.
