Abstract

The invention provides a signal processing method. The method includes: acquiring a to-be-denoised signal; detecting first waveform positions in the signal; dividing the signal into a plurality of signal segments according to the first waveform positions, wherein each signal segment includes at least one first waveform position; respectively judging and confirming signal quality of a signal in each signal segment; respectively determining a denoising method of denoising processing on the signal in each signal segment according to the signal quality of the signal in each signal segment; and using the denoising method of denoising processing on the signal in each signal segment for respective denoising processing on the signal in each signal segment. By adopting the above technical solution,matching of the denoising methods and changes of the signal quality can be ensured, denoising processing on the to-be-denoised signal is enabled to be more targeted, and denoising efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of signal processing, in particular to a signal processing method and device. Background technique [0002] When electronic equipment is used to collect signals, noise signals will inevitably be introduced, so denoising the collected signals is a necessary prerequisite for signal analysis and processing. For a signal with better signal quality, because it contains less noise, it can be denoised by a less complex denoising method to save processing time; for a signal with poor signal quality, because it contains There is a lot of noise, and a denoising method with high complexity should be used for denoising processing in order to improve the denoising effect. [0003] In the prior art, when performing denoising processing on a signal to be analyzed, people generally first observe with the naked eye, or use a simple signal analysis method to analyze the signal quality as a whole, and then select the ...
