Problems solved by technology
[0002] Signal acquisition and processing in the fields of electric power and medical treatment is an indispensable link in research work, and the noise in the environment will affect the purity of the collected signal to varying degrees, especially when the environmental noise is strong, it may even cause the signal Distortion, causing great interference to the later signal analysis work
At present, there are hardware filtering and software filtering methods for filtering noise interference in single-frequency signals. Among them, the filtering effect of hardware filtering is poor, that is, the filtered signal contains high noise components, and the system's anti-interference ability is poor; the filtering effect of software methods Better, most of the filtering work is performed in the host computer, which is less convenient for some working conditions that require on-site operations
