Hi!
I was thinking of how to convert sqaure wave in to sine and trianguler wave for wide range of frequencies. I have face this problem in a college project and i tried some thing but still today i was unable to find a proper solution.
The solution which i used was to put an RC integrator to make it approx. sine wave, but the result was very unstable and also its amplitute was very much depands on frequency of square wave.
Also i was wondering that how chips like 8038 (precise waveform generator) produce sine, square, and triangular acurately for a wide range of frequencies.
Thanks!
