  2. Symbol rate - Wikipedia

    en.wikipedia.org/wiki/Symbol_rate

    In the case of GPS, we have a data rate of 50 bit/s and a symbol rate of 1.023 Mchips/s. If each chip is considered a symbol, each symbol contains far less than one bit (50 bit/s / 1,023 ksymbols/s ≈ 0.000,05 bits/symbol). The complete collection of M possible symbols over a particular channel is called a M-ary modulation scheme.

  3. Bit error rate - Wikipedia

    en.wikipedia.org/wiki/Bit_error_rate

    The BER is the likelihood of a bit misinterpretation due to electrical noise ().Considering a bipolar NRZ transmission, we have = + for a "1" and () = + for a "0".Each of () and () has a period of .

  4. Bomb (icon) - Wikipedia

    en.wikipedia.org/wiki/Bomb_(icon)

    The bomb symbol is not used in Mac OS X, but a test application called Bomb.app, specifically written to cause a non-fatal crash, is included with Xcode and uses a rendition of the bomb symbol as its icon.

  6. Serial port - Wikipedia

    en.wikipedia.org/wiki/Serial_port

    A male DE-9 connector on an IBM PC compatible computer (with serial port symbol) used for an RS-232 serial port A female DE-9 connector on an RS-232 cable.. A serial port is a serial communication interface through which information transfers in or out sequentially one bit at a time. [1]

  7. Bit time - Wikipedia

    en.wikipedia.org/wiki/Bit_time

    The bit time for a 10 Mbit/s NIC is 100 nanoseconds. That is, a 10 Mbit/s NIC can eject 1 bit every 0.1 microsecond (100 nanoseconds = 0.1 microseconds). Bit time is distinctively different from slot time, which is the time taken for a pulse to travel through the longest permitted length of network medium.

  8. Magic Keyboard (Mac) - Wikipedia

    en.wikipedia.org/wiki/Magic_Keyboard_(Mac)

    It used an ST Microelectronics STM32F103VB 72 MHz 32-bit RISC ARM Cortex-M3 processor and included the Broadcom BCM20733 Enhanced Data Rate Bluetooth 3.0 Single-Chip Solution. It was compatible with Macs running OS X El Capitan and later, iPhones and iPads running iOS 9 or later, and TVs running Apple TV Software 7.0 or tvOS 10 or later.

  9. Code rate - Wikipedia

    en.wikipedia.org/wiki/Code_rate

    Note that bit/s is a more widespread unit of measurement for the information rate, implying that it is synonymous with net bit rate or useful bit rate exclusive of error-correction codes. See also [ edit ]
