  2. Unified Thread Standard - Wikipedia

    en.wikipedia.org/wiki/Unified_Thread_Standard

    The standard designation for a UTS thread is a number indicating the nominal (major) diameter of the thread, followed by the pitch measured in threads per inch.For diameters smaller than ⁠ 1 / 4 ⁠ inch, the diameter is indicated by an integer number defined in the standard; for all other diameters, the inch figure is given.

  3. 8b/10b encoding - Wikipedia

    en.wikipedia.org/wiki/8b/10b_encoding

    The low five bits of data are encoded into a 6-bit group (the 5b/6b portion) and the top three bits are encoded into a 4-bit group (the 3b/4b portion). These code groups are concatenated together to form the 10-bit symbol that is transmitted on the wire. The data symbols are often referred to as D.x.y where x ranges over 0–31 and y over 0–7.

  4. Calculator input methods - Wikipedia

    en.wikipedia.org/wiki/Calculator_input_methods

    Ten key input mode is available in printing calculators from companies such as Sharp, [20] and in software calculators like Judy's TenKey [21] used by accounting firms. Online tenkey training and certification tools are available as well, [ 22 ] [ 23 ] and some businesses use ten key typing speed as an employment criterion.

  5. Half-power point - Wikipedia

    en.wikipedia.org/wiki/Half-power_point

    The half-power point is the point at which the output power has dropped to half of its peak value; that is, at a level of approximately −3 dB. [1] [a]In filters, optical filters, and electronic amplifiers, [2] the half-power point is also known as half-power bandwidth and is a commonly used definition for the cutoff frequency.

  6. Algorithms for calculating variance - Wikipedia

    en.wikipedia.org/wiki/Algorithms_for_calculating...

    This algorithm can easily be adapted to compute the variance of a finite population: simply divide by n instead of n − 1 on the last line.. Because SumSq and (Sum×Sum)/n can be very similar numbers, cancellation can lead to the precision of the result to be much less than the inherent precision of the floating-point arithmetic used to perform the computation.

  7. Computation of cyclic redundancy checks - Wikipedia

    en.wikipedia.org/wiki/Computation_of_cyclic...

    As an example of implementing polynomial division in hardware, suppose that we are trying to compute an 8-bit CRC of an 8-bit message made of the ASCII character "W", which is binary 01010111 2, decimal 87 10, or hexadecimal 57 16.

  8. Sound reduction index - Wikipedia

    en.wikipedia.org/wiki/Sound_Reduction_Index

    The Sound Reduction Index is expressed in decibels (dB). It is the weighted sound reduction index for a partition or single component only. This is a laboratory-only measurement, which uses knowledge of the relative sizes of the rooms in the test suite, and the reverberation time in the receiving room, and the known level of noise which can pass between the rooms in the suite by other routes ...

  9. TI-BASIC - Wikipedia

    en.wikipedia.org/wiki/TI-BASIC

    For many applications, it is the most convenient way to program any TI calculator, since the capability to write programs in TI-BASIC is built-in. Assembly language (often referred to as "asm") can also be used, and C compilers exist for translation into assembly: TIGCC for Motorola 68000 (68k) based calculators, and SDCC for Zilog Z80 based ...
