> Given an externally generated square wave of varying > frequency(audio range) and varying amplitude, what is the best/ > easiest way of converting it to a sawtooth of the same frequency > and amplitude? One solution: Find a VCO that has a unit-amplitude sawtooth as an auxiliary output. Phase lock the VCO to the input square wave. To get the amplitude right, full-wave rectify the square wave and apply the result and the sawtooth to an analog multiplier.
