基于过采样技术提高ADC分辨率

Improving ADC Resolution Based on Over Sampling Technology

随着计算机技术的不断发展,产品的数字化、准确化程度在很多系统中起重要作用。很多系统都需要使用模数转换器ADC进行测量,将模拟信号转换为数字信号。介绍了用过采样和求均值的方法来达到较高分辨率和信噪比,提出采样技术可以在不使用昂贵的ADC芯片的情况下提高模数转换的分辨率。

Along with the continuous development of computer technology, product digitization, accuralizing degree in many systems plays an important role. Many systems requires the use of ADC measurement, will convert analog signals to digital signals. Introduces that has used the method of over sampling and the average value for us to achieve higher resolution and signal to noise ratio, puts forward sampling technology can improve the resolution of analog - to - digital conversion under the situation without the use of expensive ADC chip.
