Encoding Definition

Encoding is the conversion of signals and data based on specific rules. A word is having a meaning such as “encoding,” “encryption,” or “symbolization.”

Encoding a (or millionaire) is in a certain way to the analog signal or digital data, is to add a conversion as reversible (or similar) signal or data after.

In particular, in the field of computers (particularly personal computers ), encoding refers to compressing voice or moving images using a codec. Some may elaborate as “Enko.”

Uses

Analog signal encoding

Often used for noise reduction in recorders. For example, in dbx, it is amplified by the size of the audio signal an extraordinary amplifier factor changes records the volume change to 1/2 (logarithmically) and doubles it during playback.

The noise or distortion from the recorder and tape is short than the signal, so it becomes small and small during playback the log expands, making it harder to hear due to the music signal.

Noise reduction widely uses HiFi video and cassette recorders.

Discrete 4ch record, sub-carrier modulation, and superposition and recording are also called encoding.

Even in FM radio broadcasting, LP records, and analog tape recorders, in classical music, high-frequency components with small amplitudes were broadcast and recorded in advance.

Digital devices such as DAT, CD, and DTRS also have a function that reduces apparent quantization noise in the same way. These usually called emphasis.

There was also a device that emphasizes high frequencies to the extent that it does not touch the broadcasting law in medium wave broadcasting. See also RIAA characteristics.

Digital data encoding

En details are also referred to as encoding and are to convert digital data into code according to the purpose following a particular rule.

For further information on the encoding method, see the encoding method.

Files in a computer compression (also referred to as “high-efficiency coding”) or encrypted [1] may also see to a. In this case, the encoding function (software or hardware) is called “encoder.”

Coding is the method that makes it possible to convert a character of a natural language, into a symbol of another representation system, such as a number, applying coding rules which define, how it encodes the given system of representation.

Coding is essential for adequate inventory control, as the encoded data will allow us to achieve more efficiency because they require less time for your organization or search.

Memory is an ability to encode, store, and retrieve information. Coding allows converting perceived items that store in the brain and evoked from short-term memory or long-term memory.

For its part, working memory stores information with a view to its use or direct manipulation.

Types of coding

Alphabetical:

Encodes materials with a set of letters, each of which identifies specific characteristics and specifications. This limits the number of articles and is difficult to memorize.

Numerical:

It is the most used for its simplicity, there may be a limited number of articles, and it provides information.

Alphanumeric:

it is a combination of letters and numbers and opens a more significant amount of articles. The letters represent the class, and the group and the numbers represent the code.

Manchester coding:

it is a two-phase L coding, the method of electrical coding of a binary signal. In which the bit time is a transition between two signal levels.

It is an auto-synchronized coding since it obtains the clock signal, which makes possible precise synchronization of the data flow.

The method of electrical coding of a binary signal in which, the transition between two signal levels. And also changes made in half of the bit duration interval so that development serves synchronization procedure and data transmission.

AMI CODE (“Alternate Mark Inversion”):

They correspond to a type of coding that represents the “ones” with pulses of alternate polarity. And also, the “zeros” by the absence of vibrations.

When a positive impulse assigns to the first “1”, the next “1” assigns a contrary motivation, and so on.

Therefore, positive and negative impulses assign alternately to the logical “1”.

It is the zero return type, during the second half of the bit interval zero voltage uses “1” to represent.
