Difference between Pulse Wave and PWM ?

Click For Summary
SUMMARY

The discussion clarifies the distinction between Pulse Wave and Pulse Width Modulation (PWM). Pulse Wave, also known as Pulse Train, maintains a constant duty cycle, whereas PWM features a variable duty cycle. This fundamental difference means that Pulse Wave cannot be used interchangeably with PWM in applications requiring modulation of power or signal.

PREREQUISITES
  • Understanding of signal modulation concepts
  • Familiarity with duty cycle terminology
  • Basic knowledge of waveform characteristics
  • Awareness of applications of Pulse Width Modulation
NEXT STEPS
  • Research the applications of Pulse Width Modulation in electronics
  • Explore the mathematical principles behind duty cycle calculations
  • Learn about different types of waveforms and their uses in signal processing
  • Investigate the role of Pulse Waves in digital communication systems
USEFUL FOR

Electronics engineers, signal processing specialists, and students studying modulation techniques will benefit from this discussion.

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:
