Difference between Pulse Wave and PWM ?

Click For Summary
Pulse Wave and Pulse Width Modulation (PWM) are distinct concepts in signal processing. Pulse Wave typically has a constant duty cycle, while PWM features a varying duty cycle that allows for more control over power delivery and signal characteristics. This difference means that while they share similarities, they cannot be used interchangeably in all applications. Understanding this distinction is crucial for effective implementation in electronic designs. Clear differentiation between these two terms aids in better comprehension of their respective functionalities.

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. :)

Thread 'I thought it was only Amazon that sold unsafe junk'

I grabbed an under cabinet LED light today at a big box store. Nothing special. 18 inches in length and made to plug several lights together. Here is a pic of the power cord: The drawing on the box led me to believe that it would accept a standard IEC cord which surprised me. But it's a variation of it. I didn't try it, but I would assume you could plug a standard IEC cord into this and have a double male cord AKA suicide cord. And to boot, it's likely going to reverse the hot and...
