  2. Bit error rate - Wikipedia

    en.wikipedia.org/wiki/Bit_error_rate

    These pattern sequences are used to measure jitter and eye mask of TX-Data in electrical and optical data links. QRSS (quasi random signal source) – A pseudorandom binary sequencer which generates every combination of a 20-bit word, repeats every 1,048,575 words, and suppresses consecutive zeros to no more than 14. It contains high-density ...

  3. Binary decision diagram - Wikipedia

    en.wikipedia.org/wiki/Binary_decision_diagram

    In computer science, a binary decision diagram (BDD) or branching program is a data structure that is used to represent a Boolean function. On a more abstract level, BDDs can be considered as a compressed representation of sets or relations. Unlike other compressed representations, operations are performed directly on the compressed ...

  4. Phase-shift keying - Wikipedia

    en.wikipedia.org/wiki/Phase-shift_keying

    Timing diagram for QPSK. The binary data stream is shown beneath the time axis. The two signal components with their bit assignments are shown at the top, and the total combined signal at the bottom. Note the abrupt changes in phase at some of the bit-period boundaries. The binary data that is conveyed by this waveform is: 11000110.

  5. Binary entropy function - Wikipedia

    en.wikipedia.org/wiki/Binary_entropy_function

    Binary entropy ⁡ is a special case of (), the entropy function. H ⁡ ( p ) {\displaystyle \operatorname {H} (p)} is distinguished from the entropy function H ( X ) {\displaystyle \mathrm {H} (X)} in that the former takes a single real number as a parameter whereas the latter takes a distribution or random variable as a parameter.

  6. MATLAB - Wikipedia

    en.wikipedia.org/wiki/MATLAB

    MATLAB (an abbreviation of "MATrix LABoratory" [18]) is a proprietary multi-paradigm programming language and numeric computing environment developed by MathWorks. MATLAB allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages.

  7. Binary data - Wikipedia

    en.wikipedia.org/wiki/Binary_data

    Hence, "binary data" in computers are actually sequences of bytes. On a higher level, data is accessed in groups of 1 word (4 bytes) for 32-bit systems and 2 words for 64-bit systems. In applied computer science and in the information technology field, the term binary data is often specifically opposed to text-based data, referring to any sort ...

  8. RRDtool - Wikipedia

    en.wikipedia.org/wiki/RRDtool

    RRDtool has a graph function, which presents data from an RRD in a customizable graphical format. RRDtool (round-robin database tool) aims to handle time series data such as network bandwidth, temperatures or CPU load. The data is stored in a circular buffer based database, thus the system storage footprint remains constant over time.

  9. Butterfly diagram - Wikipedia

    en.wikipedia.org/wiki/Butterfly_diagram

    If one draws the data-flow diagram for this pair of operations, the (x 0, x 1) to (y 0, y 1) lines cross and resemble the wings of a butterfly, hence the name (see also the illustration at right). A decimation-in-time radix-2 FFT breaks a length- N DFT into two length- N /2 DFTs followed by a combining stage consisting of many butterfly operations.
