Abstract
A method and apparatus for converting a signal by reading a first signal that is represented in a first format. The first signal is used as an index into a lookup table, the first table containing entries representing signals in a second format modified by a gain. The first table outputs a second signal responsive to the index provided by the first signal, wherein the second signal is represented in a second format.
