There are several ways to evaluate the bandwidth of a signal in the time domain and frequency domain. Previously we looked at the classic relationship of rise time (t r) and bandwidth (f 3db) [Ref 1], ...

In Example IV.2.1 we studied the Fourier series for a periodic square wave: Shown below is an animation showing the influence on the addtion of terms in the Fourier series to produce this periodic ...

An audio waveform theoretically comprised of an infinite set of odd harmonic sine waves. It is often used in sound synthesis. See also: Fourier Theorem, Law of Superposition, Oscillator, Switch.

An audio waveform theoretically comprised of an infinite set of harmonically related sine waves, as shown under Law of Superposition. It is often used in sound synthesis. See also: Fourier Theorem, ...
