Bandwidth is a key concept in many telecommunications applications. In radio communications, for example, bandwidth is the frequency range occupied by a modulated carrier signal. An FM radio receiver's tuner spans a limited range of frequencies.
The consumed bandwidth in bit/s, corresponds to achieved throughput or goodput, i.e., the average rate of successful data transfer through a communication path.The consumed bandwidth can be affected by technologies such as bandwidth shaping, bandwidth management, bandwidth throttling, bandwidth cap, bandwidth allocation (for example bandwidth allocation protocol and dynamic bandwidth ...
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 bandwidth of a filter is proportional to its center frequency. In receivers like the TRF in which the filtering is done at the incoming RF frequency, as the receiver is tuned to higher frequencies, its bandwidth increases. The main reason for using an intermediate frequency is to improve frequency selectivity. [1]
A baseband bandwidth is equal to the highest frequency of a signal or system, or an upper bound on such frequencies, [3] for example the upper cut-off frequency of a low-pass filter. By contrast, passband bandwidth is the difference between a highest frequency and a nonzero lowest frequency.
The link spectral efficiency of a digital communication system is measured in bit/s/Hz, [2] or, less frequently but unambiguously, in (bit/s)/Hz.It is the net bit rate (useful information rate excluding error-correcting codes) or maximum throughput divided by the bandwidth in hertz of a communication channel or a data link.
Broadband systems usually use a different radio frequency modulated by the data signal for each band. [15] The total bandwidth of the medium is larger than the bandwidth of any channel. [16] The 10BROAD36 broadband variant of Ethernet was standardized by 1985, but was not commercially successful. [17] [18]
Frequency modulation (FM) ... their count is doubled, and then multiplied by the modulating frequency to find the bandwidth. For example, 3 kHz deviation modulated by ...
