Adau1452 Hilbert Transformer doesnt work
Thread Summary
The user encountered issues with no signal passing through the Hilbert block in Sigma Studio 4.7 and 4.5 with ADAU1701 and 1452. The problem was resolved by correctly setting the input selector switch. The user now seeks advice on building a variable phase shift or halving the 90° phase shift.AI Generated Content
Hello Friends,
My Problem is, i have tested in Sigma 4.7 and 4.5 with adau1701 and 1452.
no signal goes through the Hilbert block. inserted into existing project, no success. new simple project creates input output stimulus probe and the Hilbert block in between. there is simply no signal going through the advanced DSP structure (Hilbert Transformer). I've also used another laptop and tested the same thing, also without success. tested with adau1701 and 145x. Do I have to activate something somewhere in Sigma Studio to be able to use the Hilbert transformation. I absolutely need a 90* phase shift over the entire audio spectrum 10-25000hz. I hope you can help me. I use rev.4.7 and Windows10, thanks Eddi

Hello Eddi,
I'm not certain about what's wrong with your project but this block works as expected. You can see the image below.
As you can see, One (red) is delayed in phase by 90 degrees from the other (blue). Unfortunately, you can't plot it with stimulus and probe. So, if you have an oscilloscope, then you will be able to see it. Have you checked it with a scope?
You don't need to activate anything; you can just drag and drop the block and use it.
If you have further queries, then please attach your project as well.

Yes, i have Seen in many other Projects here.
if I have integrated stimulus and probe, a line should still be displayed in magnitude. but this doesn't happen to me. If I insert the Hilbert into my working project, the outputs remain mute, if I remove it again, music plays again. I'll try again and take some pictures tonight. thank you in advance, exactly as you have presented it, I need it thank you
I'm such an idiot. I have an input selector switch that was set incorrectly when creating the extended project with the Hilberts. in addition I removed all stimulus and probe. now the Hilbert transform works. I have another question: do you have an idea how I can easily build a variable phase shift, or halve the 90* shift, etc.?
And thank you very much
Best regards
Eddi
Hello Eddi,
I hope this post will give you some idea.
