Audio decoder converts digital audio to analog form; Binary decoder, digital circuits such as 1-of-N and seven-segment decoders; Decompress (compression decoder), converts compressed data (e.g., audio/video/images) to an uncompressed form; Instruction decoder, an electronic circuit that converts computer instructions into CPU control signals
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.
Decoder (disambiguation) Decoding methods, methods in communication theory for decoding codewords sent over a noisy channel; Codec, a coder-decoder; Recode (disambiguation) Video decoder, an electronic circuit
Given a received vector maximum likelihood decoding picks a codeword that maximizes (),that is, the codeword that maximizes the probability that was received, given that was sent.
For example, when used as an address decoder, the 74154 [3] provides four address inputs and sixteen (i.e., 2 4) device selector outputs. An address decoder is a particular use of a binary decoder circuit known as a "demultiplexer" or "demux" (the 74154 is commonly called a "4-to-16 demultiplexer"), which has many other uses besides address ...
A secret decoder ring (or secret decoder) is a device that allows one to decode a simple substitution cipher—or to encrypt a message by working in the opposite direction. [ 1 ] As inexpensive toys, secret decoders have often been used as promotional items by retailers, as well as radio and television programs, from the 1930s through to the ...
An audio codec, or audio decoder is a device or computer program capable of encoding or decoding a digital data stream (a codec) that encodes or decodes audio. [1] [2
A video decoder is an electronic circuit, often contained within a single integrated circuit chip, that converts base-band analog video signals to digital video. [1] Video decoders commonly allow programmable control over video characteristics such as hue , contrast , and saturation .
