When we think about signals and systems, we often do so with an emphasis on creating and transmitting signals with specific characteristics. That is, we want the signal to have some desired amplitude, ...

Distortion comes in two basic classes: Linear distortion, which is not an oxymoron; and nonlinear distortion, which includes all other distortions except noise. Noise is quite another matter and is ...

Just like NTSC transmitters had to deal with linear and nonlinear distortions, so do today’s DTV transmitters. The difference is that instead of the wrong color or brightness, digital distortions will ...

In Audioholic’s subwoofer reviews, our measurements are an analysis of a subwoofer's ability to accurately reproduce the source content. This involves testing its behavior with respect to linear ...

Passive intermodulation (PIM) distortion arises when non‐linearities and imperfections within electrical connectors and transmission lines cause the intermodulation of signals, leading to spurious ...
