  2. Help:Conditional tables - Wikipedia

    en.wikipedia.org/wiki/Help:Conditional_tables

    One method of hiding rows in tables (or other structures within tables) uses HTML directly. [1] HTML is more complicated than MediaWiki table syntax, but not much more so. In general, there are only a handful of HTML tags you need to be aware of

  3. Multiplexing - Wikipedia

    en.wikipedia.org/wiki/Multiplexing

    A device that performs the multiplexing is called a multiplexer (MUX), and a device that performs the reverse process is called a demultiplexer (DEMUX or DMX). Inverse multiplexing (IMUX) has the opposite aim as multiplexing, namely to break one data stream into several streams, transfer them simultaneously over several communication channels ...

  4. Multiplexer - Wikipedia

    en.wikipedia.org/wiki/Multiplexer

    Schematic of a 1-to-2 demultiplexer. Like a multiplexer, it can be equated to a controlled switch. In electronics, a multiplexer (or mux; spelled sometimes as multiplexor), also known as a data selector, is a device that selects between several analog or digital input signals and forwards the selected input to a single output line. [1]

  5. Wavelength-division multiplexing - Wikipedia

    en.wikipedia.org/wiki/Wavelength-division...

    A WDM system uses a multiplexer at the transmitter to join the several signals together and a demultiplexer at the receiver to split them apart. [1] With the right type of fiber, it is possible to have a device that does both simultaneously and can function as an optical add-drop multiplexer .

  6. Orthogonal frequency-division multiplexing - Wikipedia

    en.wikipedia.org/wiki/Orthogonal_frequency...

    The low symbol rate makes the use of a guard interval between symbols affordable, making it possible to eliminate intersymbol interference (ISI) and use echoes and time-spreading (in analog television visible as ghosting and blurring, respectively) to achieve a diversity gain, i.e. a signal-to-noise ratio improvement.

  7. Statistical time-division multiplexing - Wikipedia

    en.wikipedia.org/wiki/Statistical_time-division...

    Time domain statistical multiplexing (packet mode communication) is similar to time-division multiplexing (TDM), except that, rather than assigning a data stream to the same recurrent time slot in every TDM, each data stream is assigned time slots (of fixed length) or data frames (of variable lengths) that often appear to be scheduled in a randomized order, and experience varying delay (while ...

    en.wikipedia.org/wiki/HTML_form

    The target PHP file then accesses the data passed by the form through PHP's $_POST or $_GET variables, depending on the value of the method attribute used in the form. Here is a basic form handler PHP script that will display the contents of the first_name input field on the page: form.html

  9. Barrel shifter - Wikipedia

    en.wikipedia.org/wiki/Barrel_shifter

    It can however in theory also be used to implement unary operations, such as logical shift left, in cases where limited by a fixed amount (e.g. for address generation unit). One way to implement a barrel shifter is as a sequence of multiplexers where the output of one multiplexer is connected to the input of the next multiplexer in a way that ...
