The transmission rate of binary symbols (‘0’ and ‘1’), equal to the total number of bits transmitted in one second sent or received across a network or communications channel, abbreviated as bps (bits per second), a measure of data transmission speed
The number of bits that "pass" a given point in a telecommunication network usually within a second is referred to as a bit rate Thus, a bit rate is usually measured in some multiple of bits per second for example, kilobits, or thousands of bits per second (kbps) The term bit rate is also a synonym for data transfer rate (or simply data rate)
The speed at which binary digits (bits) would be transmit ted over a communications path and usually expressed in "bits per second" ( bps) Bit rate should not be confused with Baud which defines the rate of signal state changes
In developing an audio sound for computers or telecommunication, the bit rate (or sampling rate) is the number of samples of a sound (as an analog event) that are taken each second to represent that sound digitally The more samples taken per second, the more accurate the digital representation of the sound can be For example, the current sample rate for CD-quality audio is 44,100 samples per second This sample rate can accurately reproduce the audio frequencies up to 20,500 Hertz (cycles per second), covering the full range of human hearing
In a bit stream, the number of bits occurring per unit time, usually expressed in bits per second (188) Note: For n-ary operation, the bit rate is equal to log2n times the rate (in bauds), where n is the number of significant conditions in the signal
Bit rate is the capacity characteristic of digital signals as defined by the number of bits (or bytes) per second that a channel will support For example, a transmission facility that can support information exchange at the rate of I megabit per second (1 Mbps or 1,000,000 bits per second) delivers the same quantity of information, i e , throughput, as a 1 kilobit per second (kbps or 1,000 bits per second) facility, but, in only 1/1000 of the time
A measure of bandwidth, expressed as the number of bits transmitted per second A 28 8 Kbps modem, for example, can transmit or receive around 29,000 bits per second
Number of data bits recorded, per second, in a digital audio recording The higher the bit rate, the better (higher fidelity) the recording Most MP3s are encoded at a bit rate of 128kbps (kilobits per second) MP3 encoders (rippers) let you set higher, lower, and variable bit rates
