faasivääristused

Faasivääristymät, also known as phase distortion, refer to unwanted alterations in the phase relationships between different frequency components of a signal. In audio applications, this can lead to changes in the perceived sound quality. When a signal passes through a system that exhibits faasivääristymät, its various frequencies are not delayed by the same amount of time. This temporal shift causes the waveform to change shape, even if the amplitude of each frequency component remains unaffected.

The human ear is sensitive to phase relationships, and significant faasivääristymät can result in a less clear or "muddier" sound. In some cases, it can also affect the stereo imaging of an audio signal, making it harder to pinpoint the location of instruments in a mix. Unlike harmonic distortion, which introduces new frequencies, faasivääristymät manipulate the existing phase information.

Common sources of faasivääristymät include electrical components like capacitors and inductors, especially in analog circuits. Digital signal processing can also introduce these effects if not implemented carefully. While some level of faasivääristymät is often unavoidable in any signal processing, excessive amounts are generally undesirable in high-fidelity audio reproduction. Engineers strive to minimize these distortions to preserve the integrity of the original signal.
