A code that has n significant conditions, where n is a positive integer greater than
1.
Note 1: The integer substituted for n indicates the specific number of significant conditions, i.e., quantization states, in the code. For example, an 8-ary code has eight significant conditions and can convey three bits per code symbol.
Note 2: A prefix that indicates an… (Read More →)

See n-ary code.

An active element in the n-th layer of the Open Systems Interconnection--Reference Model (OSI-RM) that (a) interacts directly with elements, i.e., entities, of the layer immediately above or below the n-th layer, (b) is defined by a unique set of rules, i.e., syntax, and information formats, including data and control formats, and (c) performs a defined set of functions.

A defined action performed by an n-entity.
Note: An n-function may be (a) a single action, i.e., a primitive function, or (b) a set of actions.

A pseudorandom binary sequence of n bits that (a) is the output of a linear shift register and (b) has the property that, if the shift register is set to any nonzero state and then cycled, a pseudorandom binary sequence of a maximum of n = 2m-1 bits will be generated, where m is the number of stages, i.e., the… (Read More →)

A code in which the signals or groups of digits that represent coded items, such as characters, have the same number of signal elements or digits, namely n elements or digits, where n may be any positive integer.
Note: An example of an n-unit code is the 7-unit code (8-unit with parity) ASCII code. Each character is represented by a… (Read More →)

In the ISO Open Systems Interconnection--Reference Model (OSI--RM), an n+1 entity that uses the services of the n-layer, and below, to communicate with another n+1 entity.
Note: If n identifies a specific or a reference level, the n+1 layer is the layer above the n layer and the n-1 layer is the layer below the n layer. Thus, the n+2… (Read More →)
