The encoder is usually a simple circuit which has state memory and some feedback logic, normally XOR gates. The decoder can be implemented in software or firmware. The Viterbi algorithm is the optimum algorithm used to decode convolutional codes.
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 ...
Non-return-to-zero. The binary signal is encoded using rectangular pulse-amplitude modulation with polar NRZ (L), or polar non-return-to-zero-level code. In telecommunication, a non-return-to-zero ( NRZ) line code is a binary code in which ones are represented by one significant condition, usually a positive voltage, while zeros are represented ...
Convolutional code. In telecommunication, a convolutional code is a type of error-correcting code that generates parity symbols via the sliding application of a boolean polynomial function to a data stream. The sliding application represents the 'convolution' of the encoder over the data, which gives rise to the term 'convolutional coding'.
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 ...
Base32 is an encoding method based on the base-32 numeral system.It uses an alphabet of 32 digits, each of which represents a different combination of 5 bits (2 5).Since base32 is not very widely adopted, the question of notation—which characters to use to represent the 32 digits—is not as settled as in the case of more well-known numeral systems (such as hexadecimal), though RFCs and ...
Integrated Multi Format Codec (MFC) provides encoding and decoding of MPEG-4/H.263/H.264 up to 1080p@30fps and decoding of MPEG-2/VC1/MPEG-4 video up to 1080p@30fps. Alma Technologies provides ultra low latency H.264 Encoder IP cores since 2011 capable of encoding Full HD video even on low cost FPGA devices.
Nati Harnik/AP/File. Sixty people allege in new lawsuits filed in Missouri that they were abused as children by dozens of priests, nuns and others, and the man who now leads the Archdiocese of ...
