Hi all! It is my understanding (and the concept makes sense in my head) that if you take a triangle wave and a square wave of the same frequency that are perfectly in phase, if you invert the triangle only when the square wave is high, you get a sawtooth wave of exactly TWICE the frequency of the original wave. Pretty neat.
My question is, HOW would one execute this, electronically? I've played with various op-amp configurations and gotten some interesting wave forms, but never the double frequency saw. It's like you need an inverting unity gain op amp which "switches on and off" on command with the square wave. This seems like it should be fairly basic, but I'm struggling to figure out a circuit to do this.
Any help would be most appreciated!!
