How it Works »New Instructable »I need a circuit that can convert sine waves to square waves that works with a wide range of frequencies and doesn't change the frequency, for a project i am working on. I also need a circuit that can convert square waves to ramp waves that also works with a wide range of frequencies and doesn't change the frequency. Thank you in advance.

what makes an op amp convert a sine wave into a square wave?

To convert a square to a ramp, use a circuit called an integrator. This circuit is so named because the output is the integral of the input function. Remember from calculus that the integral of a constant function f(x)=K is a line g(x)=Kx +C.

This circuit is very similar to a low pass filter, and can be built from a single op amp plus a couple resistors and capacitors.

I haven't gone into tremendous detail about these two circuit here, but they are very common and well documented and should be just what you need.

Take a sine wave, square it by clipping, integrate it, its a ramp.

Take a square wave, square it by clipping, integrate it, its a ramp.

Take a ramp wave, square it by clippling, integrate it, its a triangle.

The problem is, done in analogue, keeping the integration time constant related to the period of the incoming waveform - that's VERY tricky, without a priori knowledge.

look up guitar fuzz circuits to see it in action.
