Nyquist filter — A Nyquist filter is an electronic filter used in TV receivers to equalize the video characteristics. The filter is named after the Swedish–US engineer Harry Nyquist (1889–1976). Contents 1 VSB 2 Example of a VSB 3 Demodulation problems … 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
Analog-to-digital converter — An analog to digital converter (abbreviated ADC, A/D or A to D) is an electronic integrated circuit, which converts continuous signals to discrete digital numbers. The reverse operation is performed by a digital to analog converter… … Wikipedia
Chroma subsampling — is the practice of encoding images by implementing less resolution for chroma information than for luma information, taking advantage of the human visual system s lower acuity for color differences than for luminance.[1] It is used in many video… … Wikipedia
Anti-aliasing — In digital signal processing, anti aliasing is the technique of minimizing the distortion artifacts known as aliasing when representing a high resolution signal at a lower resolution. Anti aliasing is used in digital photography, computer… … Wikipedia
Complex plane — Geometric representation of z and its conjugate in the complex plane. The distance along the light blue line from the origin to the point z is the modulus or absolute value of z. The angle φ is the argument of z. In mathematics … Wikipedia
