Electromagnetic waves are used for transmission of any message. And different kinds of waves have different noise-tolerance. If my guess is right then the noise tolerance is a property of wave which tells us how much the wave can tolerate the disruption of message. However I am not sure
But on what factors does noise tolerance depend?
I need a simple answer for the high school course.
Edit: My doubt arises from the question:
Which of the following modulated signal has the best noise-tolerance ?
