Does anyone know a basic circuit I could make so I could determine if a signal is either a saw tooth or square wave? Should I judge voltage peak to peak of a wave or the pulse? Is there a simple way to do such a thing? The frequency is on the order of 100 kHz, 10mA current source, RMS of signal is 5…

Isn't there a FFT library for Arduino?

I wonder if it would keep up.
