- 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?
- signal - Whats the relationship between harmonic distortion and . . .
This proves that harmonic distortion is related to the spectral content of that feature of the sinusoid, not to any "intermodulation " I can (and do) show an exact mathematical relationship between area and harmonic distortion, and it has nothing to do with intermodulation
- Why dont we use the third harmonic in power transmission?
And the whole thing is even further complicated by loads that either abuse the harmonic content (nonlinear loads like rectifiers), or literally don't know what to do with it (the harmonic energy just causes useless heating in motors, and maybe torque pulsation as well)

- 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

So the harmonic behaviour remains unaffected indeed! Mission accomplished NOTES BELOW N B 1: I'm no Class-F expert N B 2: As your main concern seems to be the detuning effect due to Cds C d s, I'm not looking into the effect of the transistor package lead inductance, Lout L o u t
