N UNIT CODE

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 pattern of 7 binary digits. The units may also be characters or other special signs. [ From Weik '89 ]
