In theory, bandwidth is related to data rate by: 1) Nyquist formula: data rate = 2 * bandwidth * log2 (M) ; where M is the modulation level (eg., M=4 for QPSK ). 2) Shannon formula: data rate = bandwidth * log2(1+SNR) ; where SNR is the signal to niose ratio.

Note 3: The data signaling rate (DSR) in a cable is given by the relation DSR = Σ(log) 2n)/T i summed from i = 1 to i = m where DSR is the data signaling rate, m is the number of parallel channels in the cable, n i is the number of significant conditions of the modulation in the i-th channel, and T i is the unit …
Read moreWhat is frequency and symbol rate?
In digital modulation, the Symbol Rate determines the rate (frequency) at which symbols occur . A symbol may consist of one or more bits as determined by the modulation format. For example, in a BPSK. system, each symbol represents 1 bit; in a QPSKQuadrature phase shift keying system, each symbol represents 2 bits.
Read moreWhy bandwidth is calculated?
Network bandwidth is a measurement indicating the maximum capacity of a wired or wireless communications link to transmit data over a network connection in a given amount of time . Typically, bandwidth is represented in the number of bits, kilobits, megabits or gigabits that can be transmitted in 1 second.
Read moreWhat is bandwidth and its formula?
The bandwidth of a signal is defined as the difference between the upper and lower frequencies of a signal generated . As seen from the above representation, Bandwidth (B) of the signal is equal to the difference between the higher or upper-frequency (fH) and the lower frequency (fL).

Δf=fH−fL=f2−f1=2πLR .

The bandwidth of any system is the range of frequencies for which the current or output voltage is equal to 70.7% of its value at the resonant frequency , and it is denoted by BW.
