Other AbstractThe invention discloses a method for detecting gastric electrogram slow wave signals on the basis of a recursive least squares (RLS) adaptive filter. The method comprises the following steps of: a, acquiring signals b, amplifying the signals c, converting analog signals into digital signals d, processing the signals e, preprocessing data f, estimating noises and g, processing on the basis of the RLS adaptive filter. The method has the following beneficial effects and advantages: 1, an adaptive processing filter for the gastric electrogram slow wave signals is designed by taking all noises of electrocardiograms, respiration signals, dithering and a signal amplification device as the noises of the gastric electrogram slow wave signals so as to reduce the complexity of the filter and 2, the signal reproduction after the signals pass through the adaptive filter is measured so that the accurate reproduction of the gastric electrogram slow wave signals can be finished.
