Embodiment Construction
[0043] In order to better understand the above-mentioned technical solution, the above-mentioned technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0044] EEG is to obtain the signal of brain activity by recording the electrical activity of the cortex, but the electrical activity of the brain is a very weak bioelectrical signal, which requires complex signal amplification and analog-to-digital conversion technology to be recorded outside the skull into the brain signal of neuronal activity.
[0045] In addition, due to the complex signal environment around EEG acquisition, EEG signals are susceptible to noise interference. Among them, the most common sources of noise that affect the quality of EEG signals include myoelectric activity, power frequency interference, and white noise. Specifically, the existing EEG noise methods have at least the following problems:
[0046]Certain noise sourc...
