Single-sideband modulation — (SSB) is a refinement of amplitude modulation that more efficiently uses electrical power and bandwidth. It is closely related to vestigial sideband modulation (VSB) (see below).Amplitude modulation produces a modulated output signal that has… … Wikipedia
Delta-sigma modulation — Delta sigma (ΔΣ; or sigma delta, ΣΔ) modulation is a method for encoding high resolution or analog signals into lower resolution digital signals. The conversion is done using error feedback, where the difference between the two signals is… … Wikipedia
cross modulation — Interference when a carrier signal becomes modulated by an interfering and unwanted signal as well as the wanted signal … IT glossary of terms, acronyms and abbreviations
Adjacent-channel interference — or ACI is interference caused by extraneous power from a signal in an adjacent channel. Note 1: Adjacent channel interference may be caused by inadequate filtering, such as incomplete filtering of unwanted modulation products in frequency… … Wikipedia
Kendall effect — In telecommunications the Kendall effect is a spurious pattern or other distortion in a facsimile.It is caused by unwanted modulation products which arise from the transmission of the carrier signal, and appear in the form of a rectified baseband … Wikipedia
Hadamard variance — The Hadamard variance (HVAR) is a measure of stability of clocks and oscillators. It uses 3 sample variance, not unlike the Allan variance, which uses 2 sample variance. But unlike the Allan variance, the Hadamard variance is able to converge a… … Wikipedia

Noise (electronics) — Electronic noise [1] is a random fluctuation in an electrical signal, a characteristic of all electronic circuits. Noise generated by electronic devices varies greatly, as it can be produced by several different effects. Thermal noise is… … Wikipedia
