audio amplifier as a power generator (instruction)

[kolbacict]

We need any DSP with 1st order all-pass filter with F=40kHz(Fs=>96Khz, 20khz will be also about -70deg), and golden ears.

Not using DDS, DSP, FPL, only analog circuitry.  But it seems to me, it's damn hard to do.

another option is that:

If your amplifier has one single-phase input from a sound generator, then this is what I need!
But I, sorry, did not understand, is there one or three entrances?

What should be clear here is that the circuit, essentially, is an RC low-pass filter made of R1 and C1.
We know from basic circuit analysis that the voltage phase shift in an RC circuit will vary from 0° to -90°, and simulation confirms this

It's good when we have one fixed frequency. But when we need to change it several times, it's damn difficult. The output phases will no longer be 120 degrees.

 Did you understand previous video?
Is Arduino totally unknown in Russia?
let me start easier :

Why  are you still there my friend...
I don't understand  what keeps a  person in the s*ity (Дерьмо реальность) reality  of Russia?
Even if  The beautiful West is not for you - it is a future for your children or you don't care about them much?

The answer is simple.
Because I was not lucky to be born in the RSFSR and not in the Latvian SSR, the Georgian SSR or even the Kazakh SSR.

Я немного смущен всеми моими положительными чувствами к вам. Если вы не родились в CCCP, то где вы родились?
И где Вы сейчаc живете ?

РСФСР это республика в составе СССР,самая большая,с центром в москве
и по конституции равноправная со всеми остальными. УССР, БССР,Литовской ССР etc.
