Wave Form Identifier

Sure Alain, but you'll need to use a PIC with an ADC and take multiple readings... I wouldn't like to do that with a PIC (even one running at 40MHz) trying to measure a 1MHz waveform (which is what the original question was about). If you have an ADC, it would be easier to filter the signal (R and C), to charge the Cap and measure the voltage on it (kinda PWM D/A Convertor approach). With the correct value of R, you should get SQUARE at Vmax, TRIANGLE at < V50%, and SINE somewhere above TRIANGLE but below SQUARE.

Of course Mel,

in fact, the question is : constant freq. or not ???

I'd like to start out by saying thanks to all who have replied to my post!!! Everyone has contributed invaluable information to help me solve some problems. As for the frequency, it will remain constant throught the testing period, I should have mentioned that (Sorry). Maybe after I get it working, I'll take it a step further. Comments?
