En este caso, las muestras de la seal se emplean para variar la anchura o duracin de los pulsos. Figura 2 Modulacin por ancho de pulsos PWM. Aunque no es muy utilizado, en la actualidad se emplea en transmisores modulados en amplitud, en que la modulacin se realiza primero en esta forma.

Pulse Width Modulation - learn.sparkfun.com What is Pulse-width Modulation? Pulse Width Modulation (PWM) is a fancy term for describing a type of digital signal. Pulse width modulation is used in a variety of applications including sophisticated control circuitry. A common way we use them here at SparkFun is to control dimming of RGB LEDs or to control the direction of a servo. We can Pulse Amplitude Modulation (PAM) Theory of and Its ...
