Abstract
Systems and methods are provided for providing a filtered, thermometer coded output signal from an N bit digital input, where N is an integer greater than one. A truncated lookup table provides a corresponding truncated thermometer code in response an address related to the N bit digital input. A code recovery assembly transforms the truncated thermometer code into a thermometer coded output according to a recovery bit associated with the N bit digital input.
