- What exactly are harmonics and how do they appear?
"how are harmonics generated? The signal is just "on" or "off", how are there first, third, and fifth harmonics and why do they get weaker?" Although not a satisfactory answer, you could accept the fact that any physically realizable continuous-time signal can be represented as an infinite sum of sinusoids (that's a Fourier series) Thus, any sinusoidal signal doesn't have harmonics, or it

- Why harmonic distortion and not at other frequencies?
In understanding harmonic distortion, one piece of the puzzle that is missing for me is: - why does the distortion manifest at harmonic frequencies and not other frequencies Feel free to simply point me at a textbook reading that explains it, if that's easier! I understand that non-linear loads can create distortion
- filter - What is the harmonic content of a PWM signal? - Electrical . . .
To properly design a filter for this application to hit a specific harmonic distortion target, I need to know the harmonic content of the PWM signal How can I predict what that harmonic content is?
