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
Sources of Harmonics(Odd and Even) - Electrical Engineering Stack Exchange Exploring into harmonics this post explains very nicely about the odd and even harmonics with their individual importance But what comes to my mind is: What are the sources of harmonics? Why are they generated? Here is the document from National Semiconductor giving explanation about different terms of ADCs and DACs
WHY do harmonics happen? - Music: Practice Theory Stack Exchange The answers to the question 'How do harmonics work?' were most interesting OK, that's the HOW it happens But WHY does it happen ? What is the physics here ? Why doesn't a guitar string vibrat
Even harmonics from oscillator - Electrical Engineering Stack Exchange For a fully symmetric waveform the even harmonics should cancel out but any departure from symmetry will cause the even harmonics to become present Ultimately the spectrum for a repeated impulse is a descending set of both odd and even harmonics with amplitude inversely proportional to harmonic number
How to distort a square waveform to get even harmonics? To get all of the even harmonics of the square wave's base frequency, a solution that is very rich in those harmonics is a saw-tooth wave at twice the frequency of the square wave
Filter design according to harmonics in an inverter According to the Fourier series, when AC waves of different frequencies are added to the fundamental frequency, we can obtain waves such as square and sawtooth When we filter out the harmonics in
How do harmonics work? - Music: Practice Theory Stack Exchange The harmonics that are n * k * f0 (for all k in natural numbers, and f0 the frequency of the open string) are the ones that are not muted For example if the least number of divisions for your finger placement is 3, the unmuted harmonics are (3 * f0), (6 * f0), (9 * f0), and so on
