    Harmonic Distortion in sound propagation is the disturbance caused by the certain frequencies which are not originally present in the input signal.
    For example : If you put a signal at a certain frequency into a device, any signal appearing at the output of the device that are at different frequency are harmonic distortion.

    A harmonic oscillator is a system that, when displaced from its equilibrium position, experiences a restoring force, F, proportional to the displacement, x:

    F = -k x
    For example : A block attached to a spring vertically and then stretched , it will oscillate and the system is harmonic oscillator.

    hello
    Harmonic distortion is found in both the voltage and the current waveform. Most current distortion is generated by electronic loads, also called non-linear loads. These non-linear loads might be single phase loads such as point-of-sale terminals, or three-phase as in variable speed drives.
    HARMONIC OSCILLATOR: A harmonic oscillator is a system that, when displaced from its equilibrium position, experiences a restoring force, F, proportional to the displacement, x.
