  2. Linear encoder - Wikipedia

    en.wikipedia.org/wiki/Linear_encoder

    A linear encoder is a sensor, transducer or readhead paired with a scale that encodes position. The sensor reads the scale in order to convert the encoded position into an analog or digital signal , which can then be decoded into position by a digital readout (DRO) or motion controller.

  3. Linear code - Wikipedia

    en.wikipedia.org/wiki/Linear_code

    The codewords in a linear block code are blocks of symbols that are encoded using more symbols than the original value to be sent. [2] A linear code of length n transmits blocks containing n symbols. For example, the [7,4,3] Hamming code is a linear binary code which represents 4-bit messages using 7-bit codewords. Two distinct codewords differ ...

  4. Linear network coding - Wikipedia

    en.wikipedia.org/wiki/Linear_network_coding

    Random linear network coding [9] (RLNC) is a simple yet powerful encoding scheme, which in broadcast transmission schemes allows close to optimal throughput using a decentralized algorithm. Nodes transmit random linear combinations of the packets they receive, with coefficients chosen randomly, with a uniform distribution from a Galois field.

  5. Hamming code - Wikipedia

    en.wikipedia.org/wiki/Hamming_code

    The repetition example would be (3,1), following the same logic. The code rate is the second number divided by the first, for our repetition example, 1/3. Hamming also noticed the problems with flipping two or more bits, and described this as the "distance" (it is now called the Hamming distance, after him). Parity has a distance of 2, so one ...

  6. Binary-to-text encoding - Wikipedia

    en.wikipedia.org/wiki/Binary-to-text_encoding

    The best-known is the string "From " (including trailing space) at the beginning of a line, used to separate mail messages in the mbox file format. By using a binary-to-text encoding on messages that are already plain text, then decoding on the other end, one can make such systems appear to be completely transparent .

  7. Incremental encoder - Wikipedia

    en.wikipedia.org/wiki/Incremental_encoder

    Rotary incremental encoder with shaft attached to its thru-bore opening Introduction to incremental encoders, from VideoWiki script Incremental Encoder. An incremental encoder is a linear or rotary electromechanical device that has two output signals, A and B, which issue pulses when the device is moved. [1]

  8. Convolutional code - Wikipedia

    en.wikipedia.org/wiki/Convolutional_code

    A convolutional encoder is a discrete linear time-invariant system. Every output of an encoder can be described by its own transfer function, which is closely related to the generator polynomial. An impulse response is connected with a transfer function through Z-transform. Transfer functions for the first (non-recursive) encoder are:

  9. Linear timecode - Wikipedia

    en.wikipedia.org/wiki/Linear_timecode

    Linear timecode waveform as displayed in Audacity with 80 bit data frame highlighted. The basic format is an 80-bit code that gives the time of day to the second, and the frame number within the second. Values are stored in binary-coded decimal, least significant bit first. There are thirty-two bits of user data, usually used for a reel number ...
