As part of another project, I used a typical triangle wave and comparator to get a voltage-controlled PWM signal. In order to get the characteristics of the inputWM that I wanted, I quadrupled the frequency of the triangle wave.
I think I have a way to divide by thee or two, etc. without changing the pulse width, but it is complicated. (Negative edge triggered monostable + some logic.) Does anyone know a simple way to divide by two while retaining the original pulse width. It is for servo control and must be analog.
