• Frequency domain — In electronics, control systems engineering, and statistics, frequency domain is a term used to describe the domain for analysis of mathematical functions or signals with respect to frequency, rather than time.[1] Speaking non technically, a time …   Wikipedia

• Audio signal processing — Audio signal processing, sometimes referred to as audio processing, is the intentional alteration of auditory signals, or sound. As audio signals may be electronically represented in either digital or analog format, signal processing may occur in …   Wikipedia

• Bandwidth (signal processing) — Bandwidth is the difference between the upper and lower cutoff frequencies of, for example, a filter, a communication channel, or a signal spectrum, and is typically measured in hertz. In case of a baseband channel or signal, the bandwidth is… …   Wikipedia

• Digital signal processing — (DSP) is concerned with the representation of discrete time signals by a sequence of numbers or symbols and the processing of these signals. Digital signal processing and analog signal processing are subfields of signal processing. DSP includes… …   Wikipedia

• Analog signal processing — is any signal processing conducted on analog signals by analog means. Analog indicates something that is mathematically represented as a set of continuous values. This differs from digital which uses a series of discrete quantities to represent… …   Wikipedia

• Clipping (signal processing) — An oscilloscope screen of an amplifier clipping. The amplifier should be outputting a clean sine wave with rounded tops and bottoms, but instead they are cut off flat, or clipped . Clipping is a form of distortion that limits a signal once it… …   Wikipedia

• Discrete frequency domain — A discrete frequency domain is a frequency domain that is discrete rather than continuous. For example, the discrete Fourier transform maps a function having a discrete time domain into one having a discrete frequency domain. The discrete time… …   Wikipedia

• Signal (electrical engineering) — In the fields of communications, signal processing, and in electrical engineering more generally, a signal is any time varying or spatial varying quantity. In the physical world, any quantity measurable through time or over space can be taken as… …   Wikipedia

• Signal-to-noise ratio — For signal to noise ratio in statistics, see Cohen s d. Signal to noise ratio (often abbreviated SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise. It is defined… …   Wikipedia
