  2. Encoder (digital) - Wikipedia

    en.wikipedia.org/wiki/Encoder_(digital)

    An encoder (or "simple encoder") in digital electronics is a one-hot to binary converter. That is, if there are 2 n input lines, and at most only one of them will ever be high, the binary code of this 'hot' line is produced on the n -bit output lines. A binary encoder is the dual of a binary decoder . If the input circuit can guarantee at most ...

  3. Encoding/decoding model of communication - Wikipedia

    en.wikipedia.org/wiki/Encoding/decoding_model_of...

    In the process of encoding, the sender (i.e. encoder) uses verbal (e.g. words, signs, images, video) and non-verbal (e.g. body language, hand gestures, face expressions) symbols for which he or she believes the receiver (that is, the decoder) will understand. The symbols can be words and numbers, images, face expressions, signals and/or actions.

  4. Codec - Wikipedia

    en.wikipedia.org/wiki/Codec

    A codec is a device or computer program that encodes or decodes a data stream or signal. [1] [2] [3] Codec is a portmanteau of coder/decoder. [4] In electronic communications, an endec is a device that acts as both an encoder and a decoder on a signal or data stream, [5] and hence is a type of codec. Endec is a portmanteau of encoder/decoder.

  5. Binary decoder - Wikipedia

    en.wikipedia.org/wiki/Binary_decoder

    Binary decoder. 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 ...

  6. Video codec - Wikipedia

    en.wikipedia.org/wiki/Video_codec

    A video codec is software or hardware that compresses and decompresses digital video. In the context of video compression, codec is a portmanteau of encoder and decoder, while a device that only compresses is typically called an encoder, and one that only decompresses is a decoder . The compressed data format usually conforms to a standard ...

  7. Audio codec - Wikipedia

    en.wikipedia.org/wiki/Audio_codec

    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. In software, an audio codec is a computer program implementing an algorithm that compresses and decompresses digital audio data according to a given audio file or streaming media audio coding format.

  8. Vocoder - Wikipedia

    en.wikipedia.org/wiki/Vocoder

    Specifically, in the encoder, the input is passed through a multiband filter, then the output of each band is measured using an envelope follower, and the signals from the envelope followers are transmitted to the decoder. The decoder applies these as control signals to corresponding amplifiers of the output filter channels.

  9. Seq2seq - Wikipedia

    en.wikipedia.org/wiki/Seq2seq

    It uses an encoder-decoder to accomplish few-shot learning. The encoder outputs a representation of the input that the decoder uses as input to perform a specific task, such as translating the input into another language. The model outperforms the much larger GPT-3 in language translation and summarization.
