Bandwidth may be characterized as network bandwidth, [1] data bandwidth, [2] or digital bandwidth. [3] [4] This definition of bandwidth is in contrast to the field of signal processing, wireless communications, modem data transmission, digital communications, and electronics, [citation needed] in which bandwidth is used to refer to analog ...
The Rayleigh bandwidth of a simple radar pulse is defined as the inverse of its duration. For example, a one-microsecond pulse has a Rayleigh bandwidth of one megahertz. [1] The essential bandwidth is defined as the portion of a signal spectrum in the frequency domain which contains most of the energy of the signal. [2]
Bandwidth commonly refers to: Bandwidth (signal processing) or analog bandwidth, frequency bandwidth, or radio bandwidth, a measure of the width of a frequency range; Bandwidth (computing), the rate of data transfer, bit rate or throughput; Spectral linewidth, the width of an atomic or molecular spectral line; Bandwidth may also refer to:
The widespread adoption of digital video and accompanying compression formats has reduced the bandwidth needed for a high-definition video signal (with HDV and AVCHD, as well as several professional formats such as XDCAM, all using less bandwidth than a standard definition analog signal).
In broadcast television systems, VF bandwidth, video bandwidth or more formally video frequency bandwidth is the range of frequencies between 0 and the highest frequency used to transmit a live television image.
A composite video signal combines, on one wire, the video information required to recreate a color picture, as well as line and frame synchronization pulses. The color video signal is a linear combination of the luminance (Y) of the picture and a chrominance subcarrier which carries the color information (C), a combination of hue and saturation .
Often used synonymously with the term tint. It is the dominant wavelength that distinguishes a color such as red, yellow, etc. Most commonly, video hue is influenced by a camera's white balance or scene lighting. Video color processors, such as the video equalizer, are the main tools used to adjust and correct hue problems. [1]
