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
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
EMC emission harmonics - Electrical Engineering Stack Exchange I have a crystal associated with an Ethernet-to-PCIe bridge operating at 25 MHz I observe spikes at 62 5 MHz and 312 5 MHz Those harmonics are 2 5 times and 12 5 times the crystal fundamental fre
How do I simulate an RF mixer in PSS or harmomic balance with an . . . However, I have severe trouble getting a harmonic balance or periodic-steady-state simulation to succeed with sensible results When I use the shooting engine, PSS fails to converge with messages such as the following: Conv norm = 44 7e+03, max dV(I28 net8) = 11 032 V, took 14 92 s
IIP2 Second Order Intercept Rule of Thumb I'm faced with the problem of explaining the harmonic production in a system where the second order intercept points of the cascaded components are unknown As a way to bolster my explanation, I wo
