Information on PWM

PWM , also known as pulse-length modulation (PLM) or pulse-duration modulation (PDM), is a pulse modulation technique that transmits amplitude information of an analogue signal, not by the height of the pulse (as in PAM), but by its duration.

Other topics in our resources on Communications Systems related to PWM include: 

Pulse code modulation (PCM) Alternate mark inversion (AMI) Pulse duration modulation (PDM)

Pulse amplitude modulation (PAM) Pulse length modulation (PLM)

Delta modulation Pulse position modulation (PPM)
