Abstract
A digital encoder (34) is partitioned into a plurality of rank ordered encoder circuits (36-39) which concurrently encodes least significant bits of an input signal from a first digital format to an output signal in a second digital format. Simultaneously, at least one bit of the input signal is used by a most significant bit encoder (42) to provide at least one most significant bit of the input signal in the second digital format. The at least one most significant bit is also used to select an output encoding of one of the plurality of rank ordered encoder circuits (36-39)as a remainder of the bits of the output signal in the second digital format.
