| 摘要 |
<p>The present invention relates to an ADC control method using an analog-digital convertor (ADC) control board and an ADC control system. The ADC control board includes a comparator which determines whether a noise is interposed in a sensor signal inputted to the ADC by comparing the sensor signal inputted to the ADC formed on a main board with a preset reference voltage and an ADC data acquisition control unit which transmits the sensor signal acquisition point to a CPU formed on the main board by determining the periodicity of the noise if it is determined that the noise is interposed in the sensor signal inputted to the ADC through the comparator. The present invention minimizes the influence of the periodic noise.</p> |
