I need a circuit which converts the pulse width of a DC square wave into a DC level.
I.e. if the pulse width is 5ms the DC output is 5 volt, if the pulse width is 10ms the DC output is 10 Volt, and so on.
I have read that I need to put the square wave through a low pass filter to accomplish this - but no luck so far
