A harmonic of a wave is a component frequency of the signal that is an integer multiple of the fundamental frequency. If the fundamental frequency is f, the harmonics have frequencies f, 2f, 3f, 4f, etc. Even harmonics are 2f, 4f, 6f, ... Odd harmonics are f, 3f, 5f, ... And remember: Even harmonics 2f, 4f, 6f,... are odd overtones. Odd harmonics f, 3f, 5f,... are even overtones.

Odd. Even + Even = Even Odd + Odd = Even Odd + Even = Even + Odd = Odd
odd * odd = odd answer even * even = even answer odd * even = even answer
Yes. Even + Even = Even, Odd + Odd = Even and Even + Odd or Odd + Even = Odd
even times even = even odd times odd = odd even times odd = even

Odd harmonics are theoretically the only harmonics that are produced by a push-pull amplifier, and even the level of odd harmonics should be very low.
Odd harmonics are used in certain applications, such as audio signal processing, because they can create a more complex and rich sound quality compared to even harmonics. Even harmonics tend to sound more artificial or mechanical. Additionally, odd harmonics are more prominent in natural sounds and can be perceived as more pleasing to the human ear.
Symmetrical push/pull circuits must cancel even ordered harmonics, like f2, f4, f6 and therefore promote odd ordered harmonics, like (f1), f3, f5 when driven into the nonlinear range.
harmonics is nothing but an unwanted noise or ripples.A harmonic of a wave is a component frequency of the signal that is an integer multiple of the fundamental frequency. If the fundamental frequency is f, the harmonics have frequencies f, 2f, 3f, 4f, etc. For example, if the fundamental frequency is 50Hz, the frequencies of the harmonics are: 50 Hz, 100 Hz, 150 Hz, 200 Hz, etc. Don't forget: Even harmonics 2f, 4f, 6f,... are odd overtones. Odd harmonics f, 3f, 5f,... are even overtones. Scroll down to related links and look at "Calculations of harmonics from fundamental frequency".
The odd harmonic are the predominate harmonics, their current from each phase in a four-wire wye or star system will be additive in the neutral, instead of cancelling can result in current harmonic distortion levels over 30%.
A square wave is the sum of all odd harmonics of the fundamental frequency.A sawtooth or ramp wave is the sum of all even harmonics of the fundamental frequency.
Overtones are higher frequency components that result from vibrating objects producing multiple frequencies, including the fundamental frequency. Harmonics specifically refer to the multiples of the fundamental frequency produced by a vibrating object. In other words, harmonics are a subset of overtones.
There is a little problem in counting the harmonics and the overtones. So you find different statements in the internet. Some are wrong and some are right. Scroll down to related links and look at "Calculations of Harmonics from Fundamental Frequency".
In a tube closed at one end, only odd harmonics are produced. This is because the closed end acts as a node for the pressure wave, leading to a fundamental frequency and odd harmonics of that frequency.
Scroll down to related links and look at "Harmonics and overtones in comparison" or scroll down to related links and look at "Calculations of Harmonics from Fundamental Frequency". http://www.sengpielaudio.com/calculator-harmonics.htm Besides the fundamental "even harmonics" bring here the added tones: c , c, g, c, e, g , bflat, c :-) and "uneven harmonics" bring here the tones: g, e, bflat, d, f#, aflat, b ;-( Which of those both rows will be more pleasing? You can see it. Even harmonics sound more brilliant. Don't mix up harmonics with overtones! Even harmonis are uneven overtones and uneven harmonics are even overtones. Better stay with the word harmonics.
When discussing harmonics in relation to transformers, generally you're thinking of harmonics in the current waveform - if it's a 60Hz transformer, the 2nd harmonic would be 120Hz, and is usually very high on transformer energization (referred to as inrush current). The nonlinearity of the core can result in core saturation under multiple different conditions, which tend to produce harmonic currents.
Odd. Even + Even = Even Odd + Odd = Even Odd + Even = Even + Odd = Odd
