Meriachee, An R/C network attached to a pwm output will integrate the signal and turn it into an analog representation of the pwm value in percent between the full scale output voltage and 0. If you are talking about servos used for r/c control, most of them require a continuous series of pulses that are approx. 1.5 milliseconds wide and have a period of approx. 20 milliseconds.. The pulse width varies from about 1 millisecond to about 2 milliseconds. I think this is where you are getting confused....
