Discrete Analog Signal Processing

См. также в других словарях:

  • 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

  • Signal processing — is an area of systems engineering, electrical engineering and applied mathematics that deals with operations on or analysis of signals, in either discrete or continuous time. Signals of interest can include sound, images, time varying measurement …   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

  • Sampling (signal processing) — Signal sampling representation. The continuous signal is represented with a green color whereas the discrete samples are in blue. In signal processing, sampling is the reduction of a continuous signal to a discrete signal. A common example is the …   Wikipedia

  • Quantization (signal processing) — In digital signal processing, quantization is the process of approximating a continuous range of values (or a very large set of possible discrete values) by a relatively small set of discrete symbols or integer values.More specifically, a signal… …   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 Fourier transform — Fourier transforms Continuous Fourier transform Fourier series Discrete Fourier transform Discrete time Fourier transform Related transforms In mathematics, the discrete Fourier transform (DFT) is a specific kind of discrete transform, used in… …   Wikipedia

  • Analog multiplier — In electronics, an analog multiplier is a device which takes two analog signals and produces an output which is their product. Such circuits can be used to implement related functions such as squares (apply same signal to both inputs), and square …   Wikipedia

  • Discrete Fourier series — A Fourier series is a representation of a function in terms of a summation of an infinite number of harmonically related sinusoids with different amplitudes and phases. The amplitude and phase of a sinusoid can be combined into a single complex… …   Wikipedia

  • Analog sound vs. digital sound — Analog sound versus digital sound compares the two ways in which sound is recorded and stored. Actual sound waves consist of continuous variations in air pressure. Representations of these signals can be recorded in either digital or analog… …   Wikipedia

  • Discrete signal — Discrete sampled signal Digital signal (Discrete here …   Wikipedia
