DIGITAL-TO-ANALOG CONVERTER |
摘要 |
<p>A digital-to-analog converter for generating output waveforms with less distortion without the need for high-speed components. The digital-to-analog converter comprises four data holding sections, four step function generators, an adding section, a D/A converter, two integrators and a timing controller. Four digital data successively inputs are held in the data holding sections, respectively, and the step function generators generate step function whose values corresponding to the held data. The adding section sums the step functions generated in the step function generators, and the D/A converter generates the analog stepwise voltage corresponding to the summed value. The two integrators integrate this combined waveform two times, thus producing a continuous analog voltage that connects the input digital data smoothly. <IMAGE></p> |
