Difference between Pulse Wave and PWM ?

  1. Feb 13, 2012 #1
    Hi! I have been getting really confused about this one thing. Can someone please clear my confusion ?
    Is there a difference between Pulse Wave and Pulse Width Modulation? If yes, what is it ? If no, can one be used in place of the other ? :smile:
    Thanx !

    It looks like the Pulse Wave or Pulse Train has constant duty cycle, as opposed to PWM where the duty cycle varies:

    Hey! Thanx! I read the wiki article before but your single line there was more helpful. :)
