Information on PDM

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


Other topics in our resources on Communications Systems related to PDM include: 
 
  • Pulse code modulation (PCM)
  • Alternate mark inversion (AMI)
  • Pulse amplitude modulation (PAM)
    		•
  • Pulse length modulation (PLM)
  • Delta modulation
    		•
  • Pulse position modulation (PPM)
  • Pulse width modulation (PWM)
