- 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? Is it going to vary dramatically with the pulse widths? Or will there be certain simplifying assumptions I can make?

Calculate total harmonic distortion Ask Question Asked 5 years, 1 month ago Modified 1 year, 7 months ago
- 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
- what causes voltage harmonics - Electrical Engineering Stack Exchange
People keep telling me that Nonlinear loads causes current harmonics and when i ask them about what causes voltage harmonics, they tell me wherever there is current harmonics there is voltage harmo
- failure - Harmonics are bad. . . But how bad? - Electrical Engineering . . .
The harmonic effects being controlled are long-term effects (overheating of cables, motors, transfomers, capacitors, etc ) over a period of minutes, and short-term effects on electronic devices over a period of seconds
- signal - Harmonic detection using lock-in amplifier - Electrical . . .
0 Can a third harmonic of a signal be detected using a lock-in amplifier under the same parameters fixed for collecting the fundamental or the parameters needs to be adjusted Here by parameters I mean sensitivity , time constant and phase I am using a Mach-zehnder interferometer to intensity modulate my laser beam which is pulsed at 80 Mhz rep
