Embodiment Construction
[0043] The present invention will be described in further detail below in conjunction with specific examples. It should be understood that these embodiments are used to illustrate the basic principles, main features and advantages of the present invention, and the present invention is not limited by the scope of the following embodiments. The implementation conditions used in the examples can be further adjusted according to specific requirements, and the unspecified implementation conditions are usually the conditions in routine experiments.
[0044] In order to improve the AD sampling resolution of mainstream microcontrollers (built-in low-precision 10-bit or 12-bit AD conversion modules), the present invention proposes a high-precision processing method for AD sampling signals and reduces the cost of obtaining high-resolution AD sampling. The method can simultaneously deal with the signal aliasing problem and effectively reduce the influence of signal jitter.
