| Abstract: | It is needed in the computerized control system to convert analog signal into digtal signal, so A/D conyertor is an essential component. A cheap. highrate A/D convertor of low resolution can be converted into a high-rate A/D convertor of high resolution by prediction-correction two steps of A/D conversion and the cost of hardware system is reduced. |
