In digital electronics, a binary decoder is a combinational logic circuit that converts binary information from the n coded inputs to a maximum of 2 n unique outputs. They are used in a wide variety of applications, including instruction decoding, data multiplexing and data demultiplexing, seven segment displays, and as address decoders for memory and port-mapped I/O.

To decode an Elias omega-encoded positive integer: Start with a variable N, set to a value of 1. If the next bit is a "0" then stop. The decoded number is N. If the next bit is a "1" then read it plus N more bits, and use that binary number as the new value of N. Go back to Step 2.
QR codes which contain binary data will sometimes store it encoded in Base64 rather than simply storing the raw binary data, as there is a stronger guarantee that all QR code readers will accurately decode text, as well as the fact that some devices will more readily save text from a QR code than potentially malicious binary data.
The Chinese telegraph code, Chinese telegraphic code, or Chinese commercial code (simplified Chinese: 中文电码; traditional Chinese: 中文電碼; pinyin: Zhōngwén diànmǎ or simplified Chinese: 中文电报码; traditional Chinese: 中文電報碼; pinyin: Zhōngwén diànbàomǎ) [1] is a four-digit decimal code (character encoding) for electrically telegraphing messages written with ...
Consider the received word = (, …,) [] which was corrupted by a noisy channel.The following is the algorithm description for the general case. In this algorithm, we can decode y by just declaring an erasure at every bad position and running the errors and erasure decoding algorithm for on the resulting vector.
11B-X-1371 is a 2015 viral video sent to GadgetZZ.com, the Swedish tech blog that publicized it. The black-and-white segment is two minutes in length; its title came from the plaintext of a base64 string written on the DVD.
Informally, this means that the set of queries required to decode any given bit are uniformly distributed over the codeword. Local list decoders are another interesting subset of local decoders. List decoding is useful when a codeword is corrupted in more than δ / 2 {\displaystyle \delta /2} places, where δ {\displaystyle \delta } is the ...
