Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] An anti-jamming signal transmission method, comprising the steps of:

[0023] S1: The digital signal processing chip sends the transmission signal to the local oscillator of the transmission phase-locked loop in advance through the transmission line. The local oscillator of the transmission phase-locked loop collects the transmission signal through the acquisition module to obtain a stable transmission signal. The EEG acquisition module uses a low-pass input filter Filter out AC interference, and use compensation measures for DC series mode interference;

[0024] S2: The preamplifier module of the acquisition m...
