What is bit rate?

Bit Rate

In telecommunications and computing, bit rate (sometimes written bitrate or as a variable R) is the number of bits that are conveyed or processed per unit of time.

Bit Rate - Multimedia - Notes
... protocols, overheads, encoding schemes, etc.) the actual bit rates used by some of the compared-to devices may be significantly higher than what is listed above ...
Symbol Rate - Modulation - Data Rate Versus Error Rate
... The bandwidth depends on the symbol (modulation) rate (not directly on the bit rate) ... As the bit rate is the product of the symbol rate and the number of bits encoded in each symbol, it is clearly advantageous to increase the latter if the former is fixed ... However, for each additional bit encoded in a symbol, the constellation of symbols (the number of states of the carrier) doubles in size ...
Comparison Of Wireless Data Standards - Peak Bit Rate and Throughput
... throughput, there is often a distinction between the peak data rate of the physical layer, the theoretical maximum data throughput and typical throughput ... The peak bit rate of the standard is the net bit rate provided by the physical layer in the fastest transmission mode (using the fastest modulation scheme and error ... for end user is clearly lower than the peak data rate due to higher layer overheads ...
Bandwidth (computing) - Network Bandwidth Capacity
... Bandwidth sometimes defines the net bit rate (aka ... peak bit rate, information rate or physical layer useful bit rate), channel capacity, or the maximum throughput of a logical or physical communication path in a digital communication system ... The reason for this usage is that according to Hartley's law, the maximum data rate of a physical communication link is proportional to its bandwidth in hertz, which is sometimes called frequency bandwidth ...
Audio Bit Depth - Bit Rate - Calculating Values
... An audio file's bit rate can be calculated given sufficient information ... Bit rate = (sampling rate) × (bit depth) × (number of channels) E.g ... for a recording with a 44.1 kHz sampling rate, a 16 bit depth, and 2 channels (stereo) 44100 × 16 × 2 = 1411200 bits per second = 1411.2 kbit/s The eventual file size of an audio recording ...

Famous quotes containing the words rate and/or bit:

    Unless a group of workers know their work is under surveillance, that they are being rated as fairly as human beings, with the fallibility that goes with human judgment, can rate them, and that at least an attempt is made to measure their worth to an organization in relative terms, they are likely to sink back on length of service as the sole reason for retention and promotion.
    Mary Barnett Gilson (1877–?)

    I well recall my horror when I heard for the first time, of a journalist who had laid in a pair of what were then called bicycle pants and taken to golf; it was as if I had encountered a studhorse with his hair done up in frizzes, and pink bowknots peeking out of them. It seemed, in some vague way, ignominious, and even a bit indelicate.
