Generally the wider the bandwidth the faster it is. So, digital networks are measured in Bits Per Second or bps. What does high bandwidth mean Information and translations of high bandwidth in the most comprehensive dictionary definitions resource on the web. To use another analogy, throughput is like the amount of water you can fill in a bucket within a certain amount of time, and bandwidth is like the size of the pipes through which the water is flowing. After all, you are not particularly interested in the shape of the digital signal but rather how much information can the network handle. Bandwidth is a measurement of the amount of data that can be transmitted simultaneously. In theory you could define the bandwidth of a digital system in terms of frequency, but it is far more useful to describe bandwidth in terms of bits per second.
Bandwidth definition tv#
Which means all the video and audio signals for a TV channel resides in this set of frequencies. For instance a typical PAL television channel has a bandwidth of 8 Megahertz. Narrowband vs Wideband This brief analysis has already uncovered a problem. High-speed Internet connection known as broadband (broad bandwidth) is defined by download speeds of at least 768 Kbps and upload speeds of at least 200.
A frequency-domain representation of a signal composed of two single-frequency sine waves. In the analogue domain, it is measured in 'Hertz' or Cycles Per Second. This band refers to a band, or range, of frequencies, and width refers to the appearance of this band when viewed in the frequency domain. The method might be analogue such as radio or it might be digital such as a computer network.īandwidth is a measure of the capability of a communication channel to transmit information. Any communication channel has to be able to transmit information from one location to another. The speed of a network is defined as the bit rate of the circuit, determined by the physical signal speed of the medium.
