1. A method for removing high-frequency radio frequency interference, comprising:
acquiring an electroencephalogram signal;
performing high-pass filtering on the electroencephalogram signal to obtain an intermediate signal;
obtaining a time-domain feature of the intermediate signal within a first preset duration, and calculating a detection threshold value according to the time-domain feature;
obtaining a sub-intermediate signal within a second preset duration, and determining a signal type of the sub-intermediate signal according to the detection threshold value, wherein the signal type is determined among different signal types reflecting at least three different degrees of interference on the electroencephalogram signal; and
performing, according to the determined signal type, corresponding processing on the electroencephalogram signal corresponding to the sub-intermediate signal.
