- 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
- How do I calculate THD? - Electrical Engineering Stack Exchange
I want to calculate the total harmonic distortion of the signal using this graph and formula The formula is taken from this page: Calculating harmonic distortion First Question: So my problem is to
- 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?
- Help me understand FFT and harmonic distortions - Electrical . . .
I'm new to FFT and harmonic distortions I'm dealing with a power system where the phase currents are distorted Now I don't understand the concept of FFT and why the harmonics seen in FFT relate
- signal - Whats the relationship between harmonic distortion and . . .
Harmonic Distortion is not related to intermodulation distortion Here is another point I make, if you remove part of a sine wave, the harmonic spectrum exactly matches the harmonic content of that feature Here is a shot of the peak of a sine wave clipped off, all by itself and its spectrum Notice that the spectral pattern exactly matches the pattern of harmonic distortion of the clipped
- How Exactly Does a Push-pull Pair Cancel Even Harmonics?
As far as I can make out, it's favoured because it has low harmonic distortion and this, it seems, is down to it's push-pull configuration It's often said that a push-pull pair cancels even harmonics, but I'm interested to know exactly how this happens
