It most commonly refers to the number of pulses per second occurring in various electronics devices. At room temperature and pressure, the mean free path of a given molecule is normally only a few nanometers, which corresponds to roughly a billion collisions per second. Early computer processors and slower CPUs can only execute one instruction per clock cycle, but modern processors can execute multiple instructions per clock cycle. Unshielded twisted pair cabling, or UTP cabling, is the most common type of network cabling. o Gigaflops= 109 arithmetic operation per second. Found inside – Page 196pps (1) Pulses Per Second.

In this case, the gross bit rate is equal to the symbol rate or pulse rate of 125 megabaud, due to the NRZI line code. In modems and wireless systems, link adaptation (automatic adaption of the data rate and the modulation and/or error coding scheme to the signal quality) is often applied. Information transmission rate expressed in bits per second. The bit rate of PCM audio data can be calculated with the following formula: For example, the bit rate of a CD-DA recording (44.1 kHz sampling rate, 16 bits per sample and two channels) can be calculated as follows: The cumulative size of a length of PCM audio data (excluding a file header or other metadata) can be calculated using the following formula: The cumulative size in bytes can be found by dividing the file size in bits by the number of bits in a byte, which is eight: Therefore, 80 minutes (4,800 seconds) of CD-DA data requires 846,720,000 bytes of storage: The MP3 audio format provides lossy data compression. The clock speed is measured in Hz, often either megahertz (MHz) or gigahertz (GHz). In telecommunications and computing, bit rate (bitrate or as a variable R) is the number of bits that are conveyed or processed per unit of time.. An example of pure DC is the current produced by an electrochemical cell. {\displaystyle 2^{N}} T The number of complete AC cycles per second is the frequency, which is measured in hertz. In ultra high vacuum, the mean free path is a few thousand kilometers, which means a collision should only occur once every 20 to 30 minutes. Found insideIn the 1950s a listener might hear hundreds of pulses per second. Then that became thousands, ... The listener has to disentangle that mess into files representing, he hopes, particular radars (in modern systems, computer files). The output of a power-supply rectifier, prior to filtering, is an example of pulsating DC. Most other digital carrier-modulated schemes, for example ASK, PSK, QAM and OFDM, can be characterized as double sideband modulation, resulting in the following relation: In case of parallel communication, the gross bit rate is given by.

The bitrate depends on several factors: Generally, choices are made about the above factors in order to achieve the desired trade-off between minimizing the bitrate and maximizing the quality of the material when it is played. For realtime streaming multimedia, the encoding bit rate is the goodput that is required to avoid interrupt: The term average bitrate is used in case of variable bitrate multimedia source coding schemes. The net bit rate of the Ethernet 100Base-TX physical layer standard is 100 Mbit/s, while the gross bitrate is 125 Mbit/second, due to the 4B5B (four bit over five bit) encoding.
