If you have ever read advanced textbooks or papers about electronics, you may have been surprised to see the use of complex numbers used in the analysis of AC circuits. A complex number has two parts: ...
A phase vector or phasor in physics and engineering signifies a sine wave whose amplitude and frequency are time-variant. The behavior of a sinusoid is decomposed by phasors into three independent ...
The word phase has a clear definition for pure traveling sinusoidal waves. This is not the same for music signals since all equalizers shift phase with frequency. Sinusoidal waveforms of the same ...
