Hi all,,

I have scheme here... i forgot WHERE i have downloaded this .. here goes..

What is the function of P4 and P2???

could someone translate the text??

thanks a lot....

Hi
I dont know germany language but as i see in diagram i think:
P2 change output duty cycle and
P4 change triangular amplitude.

Hello Davood,

hmmm.. so I assume P1 would be the frequency adjustment as P2 is the duty cycle control....

looks like ill have 2 controls for triangle amplitude control..... P4 AND P3....

am I correct??

anyways, ill do give the circuit a try.....

Hi
as you said P1 adjust frequency.
and P4 adjust amplitude of all 3 waveform
whereas P3 adjust triangular amplitude

hello Davood,

P4 also adjusts SINE amplitude? since it takes a part of the triangle to form sine....

btw, I forgot to ask, whats the use of S3????

Sine wave amplitude limited with D1 and D2.
i think S3 select which portion of wave to act on duty cycle adjustment (i mean high or low value of square wave ).
