I need a circuit to take in a PWM signal (Vin) and output the average
voltage (Vo = D*Vin). Any ideas?

a RC servo driving a pot does that

**  Be careful:   the modulated pulse signal that RC servos operate from is
a  " PPM " one  -   for  " Pulse Position Modulation "  &  not PWM.

With PPM,  the high period varies from 1 to 2 mS with a repetition rate of
circa 50 Hz.

There is also a frame pulse that sets the number of servos to be controlled.
