Over sampling and Used in Temperature Compensation for Acceleration Sensor

摘要：

In the test system,a lot of analog tests in need of the A/D conversion. There are two key indicators in A/D conversion,they are effective resolution and signal to noise ratio. Through the theoretical analysis of Over-sampling theorem,and the characteristics of white noise signal,A/D converter add 1 each time,the resolution can be 4 times the sampling frequency of over-sampling to achieve. Actual in the temperature test system,using ATmegal6 embedded 10-bit ADC,which can successful implementation of a 12-bit ADC conversion accuracy,and improve the measurement resolution.
