Hi,
We wish to get a unipolar sinusoidal reference....ie like a rectified sine....we only want 1vpk...and preferably variable to eg 0.9vpk etc.
Also 50Hz...but it will be 100Hz because its a train of positive sine "halves".
{EDIT...it doesnt have to provide any power}
Which cheap, small PIC can be programmed to give a sinusoidally varying PWM so that we can filter it and get our half sine pulse train?
Can any PIC do this?
