Abstract
An apparatus generates one-dimensional dither values for dithering linear digital signals where each digital signal having an address and a signal value. The apparatus includes a counter incremented for each sequential address of the digital signals. A predetermined number of least significant bits from the current values of the counter are selected and reversed wired to generate dither values that are applied to the corresponding signal values.
