DEFINITION

Classification: 341/126

ANALOG TO OR FROM DIGITAL CONVERSION:

(under the class definition) Subject matter wherein analog information represented by the amplitude of an electrical signal, which signal can have an infinite number of values within a given range is converted to or from a coded digital signal representing the same information.
