A PWM sine wave is easy to write code for. But did you know that it wouldn't be too much harder to write code that generated a PWM sine wave at different amplitudes? If you did that, you'd only need one PIC to get what you want and variable depth of modulation too.

If you had to do it in analog, take a look at AD633 from analog devices.

I need to amplitude modulate the audio frequency output from one
16F28A PIC with a subaudio frequency from a second one. Both are PWM generated sinewaves.What is the simplest way to do this with external components?
Variable modulation depth would be useful if there's not much extra to it.
Any advice would be much appreciated.
