Abstract
A method and an apparatus analogically output low-resolution digital signals to achieve an equal analog output result of a high-resolution digital signal under a request of signal quality. The low-resolution digital signals are compensatively output multiple times to gain the energy thereof equal to the energy output by the high-resolution digital signal. Therefore, a digital-to-analog conversion with fewer bits satisfies a higher demand for accuracy generally achieved by a digital-to-analog conversion with more bits.
