"Sound" existing in this world is created by vibration of objects such as air and water. A site that can interactively know such "sound formation" is "Let's Learn About Waveforms"is. On this site, it ...

I became aware of harmonics and the sound of different shaped waveforms early in my electronics career (mid 1970’s) as I was an avid fan of [Emerson Lake and Palmer], [Pink Floyd], [Yes], and the list ...

At one time, almost all electrical loads were linear — those that weren't made up such a small portion of the total that they had little effect on electrical system operation. That all changed, ...

The representation of a PERIODIC sound or WAVEFORM as a sum of Fourier components (i.e. pure SINUSOIDAL WAVEs). According to the FOURIER THEOREM, periodic sound may be shown to consist of SINE WAVEs ...

Two WAVEFORMs combine in a manner which simply adds their respective AMPLITUDEs LINEARally at every point in time. Thus, a complex SPECTRUM can be built by mixing together different SINE WAVEs of ...
