A tag is a keyword or label that categorizes your question with other, similar questions. Using the right tags makes it easier for others to find and answer your question.
a filter that self-adjusts its transfer function according to an optimization algorithm driven by an error signal.
a method expressed in a finite list of steps of well-defined instructions to process a signal.
In signal processing and related disciplines, aliasing refers to an effect that causes different signals to become indistinguishable (or aliases of one another) when sampled.
for questions related to filters that change the phase relationship of a signal, but does not change the gain (amplitude) of the signals.
Audio, or in terms of signal processing, an audio signal is an analog or digital representation of sound, typically as an electrical voltage.
the cross-correlation of a signal with itself.
a signal processing technique applied in the time domain, intended to increase the strength of a signal relative to noise that is obscuring it.
a device that passes frequencies within a certain range and rejects (attenuates) frequencies outside that range.
the difference between the upper and lower frequencies in a contiguous set of frequencies
for any question regarding or utilizing Bayesian Estimation (Bayesian Estimator). This family includes (Among others) the Kalman Filter, the MAP Estimator and the MMSE.
Forming a beam (directional gain) and, sometimes, shifting the beam direction.
