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, ...

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

Amplifiers are specified by multiple characteristics including gain, frequency response or bandwidth, power output, linearity, efficiency, noise, and input/output impedances. In wireless applications, ...

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 ...

Achieving unidirectional signal flow—where information travels in only one direction—is vital for next-generation communication systems. Micromechanical devices leveraging parity-time (PT) symmetry ...

Unless you are a hermit or a Stylite, robust interaction with your neighbors is usually a good thing. Of course, this is not the case with broadcast transmitters, where living in isolation is usually ...

This report describes a mechanism by which non-linear distortion of the video-frequency signal in television receivers using the intercarrier sound technique can produce interference in the sound ...
