The .000001% of use cases for a simple passive VGA to HDMI is for when the video source is designed especially to output both VGA and HDMI. In these cases the cable will accompany the video source when you buy it. This is so rare, I almost regret writing this much about it. Analog vs Digital.
Definition - What does Pulse Width Modulation (PWM) mean? Pulse-width modulation (PWM) is a modulation process or technique used in most communication systems for encoding the amplitude of a signal right into a pulse width or duration of another signal, usually a carrier signal, for transmission.
One of the best example application of pulse width modulation is to use PWM for motor speed control. This technique of modifying the width of the pulse to get the desired duty cycle is called âPulse width modulationâ.
