Distortion: An undesired change in the signal's waveform after it passes through a device or a system. The same source also provides a more elaborate definition: Distortion can occur because the ...

As we’ve traced our no-nonsense path through the world of Hi-Fi audio, we’ve started with the listener, understood the limitations of the human ear, and thence proceeded to the loudspea… ...

Linear distortion is not always bad. There are two kinds of linear distortions that are frequency-dependent changes in amplitude and delay. They are linear in that gain and delay can be measured at ...

Abstract. Measurements of the non-linear distortion products generated by a system, such as a loudspeaker, which has more than one degree of freedom must be made as a continuous function of ...

Linear distortion changes the signal's amplitude and phase. In applications where those parameters are important, such as audio engineering, correcting for linear distortion is limited only by the ...

An illustration of the actual effect of nonlinear distortion in communications channels is shown in Figure 4a. Click to Enlarge Image Figure 4a: 128-QAM constellation after propagating through a ...

Non-linear distortion tends to be quite level-dependent. As such, non-linear distortion levels - for a given input signal level - can be reduced by employing multiple drivers (such as found Wilson ...

Operation of these devices represents a double-edged sword. Although they provide greater efficiency, they can also cause serious consequences to power distribution systems — in the form of harmonic ...

As a countermeasure to this non-linear distortion, an analog-type linearizer can be mounted in a stage prior to the amplifier so that the linearity of input/output characteristics can be improved ...

Unlike linear distortion, nonlinear distortions are caused within the transmitter’s power amplifier; also unlike linear distortions, nonlinear distortions cannot be corrected for by the DTV receiver ...
