# What is the difference between an overtone and a harmonic?

The term

**harmonic**has a precise meaning - that of an integer (whole number) multiple of the fundamental frequency of a vibrating object. The term**overtone**is used to refer to any resonant frequency above the fundamental frequency - an**overtone**may or may not be a**harmonic**.A.

### What do you mean by harmonic?

A

**harmonic**is a signal or wave whose frequency is an integral (whole-number) multiple of the frequency of some reference signal or wave. This frequency, usually expressed in hertz , is the frequency at which most of the energy is contained, or at which the signal is defined to occur.#### What is harmonics in power electronics?

**Harmonics**are a distortion of the normal**electrical**current waveform, generally transmitted by nonlinear loads. Switch-mode**power**supplies (SMPS), variable speed motors and drives, photocopiers, personal computers, laser printers, fax machines, battery chargers and UPSs are examples of nonlinear loads.#### What is the meaning of harmonic function?

In mathematics, mathematical physics and the theory of stochastic processes, a**harmonic function**is a twice continuously differentiable**function**f : U → R where U is an open subset of R^{n}that satisfies Laplace's equation, i.e.#### What is harmonics in induction motor?

**Harmonics**in an**Induction Motor**. Space**harmonics**fluxes are produced by the windings, slotting, magnetic saturation, inequalities in the air gap length. These**harmonic**fluxes induce voltages and circulate**harmonic**currents in the rotor windings. The resultant air gap flux is free from third**harmonics**and its multiples.

### What is a harmonic wave?

A

**harmonic**of such a**wave**is a**wave**with a frequency that is a positive integer multiple of the frequency of the original**wave**, known as the fundamental frequency. The original**wave**is also called the 1st**harmonic**, the following**harmonics**are known as higher**harmonics**.#### What is simple harmonic?

In mechanics and physics,**simple harmonic**motion is a special type of periodic motion or oscillation motion where the restoring force is directly proportional to the displacement and acts in the direction opposite to that of displacement. The motion is sinusoidal in time and demonstrates a single resonant frequency.#### How are standing waves formed on a string?

The result of the interference of the two**waves**above is a new**wave**pattern known as a**standing wave**pattern.**Standing waves**are**produced**whenever two**waves**of identical frequency interfere with one another while traveling opposite directions along the same medium.#### What is an overtone in music?

An**overtone**is any frequency greater than the fundamental frequency of a**sound**. Using the model of Fourier analysis, the fundamental and the**overtones**together are called partials. In simple cases, such as for most musical instruments, the frequencies of these tones are the same as (or close to) the harmonics.
