Manchester encoding is a digital encoding used in data transmission, where data bits are represented by a series of states. It involves setting perimeters for self-synchronization and determining the state of the bit based on the direction of transmission. It reduces errors and improves reliability, but may transmit more data bits than the original signal. […]
Character encoding is the method used to represent characters, glyphs, or symbols as numeric values in computer memory. It is necessary to translate non-numeric characters into a form that a computer can manipulate. HTML documents define the type of character encoding used, and Unicode is the standard encoding. Early computers stored basic English characters in […]
Modulation changes radio signal properties to transmit data. Types include amplitude, frequency, and phase shift coding. Amplitude-shift keying is used in digital modulation. Modulated signals have jagged discontinuities causing intersymbol interference, which can be cancelled out by equalizing or filtering received signals or designing bandwidth-limited transmit pulses. Amplitude-shift coding does not have a constant envelope. […]
Binary coding is a system of ones and zeros used to program computers. It is based on bits, with a byte being eight bits. Binary codes are stored in different ways and can represent different information. Binary coding is also used in genetic algorithms. Binary coding is a type of code primarily used to program […]
Block coding is a form of forward error correction that converts messages into specific codes and sends them as a block of data with a predetermined length. This reduces errors caused by noise during transfer and allows messages to be decipherable when they arrive. Hamming weight and distance are used to determine the likelihood of […]
