Abstract
A biological signal processing system for extracting differential signals for alternating signals detected by at least two sensors, and analyzing and processing a plurality of frequency components contained in the differential signals within a predetermined time span, in which a low-pass filter to which the alternating signals are inputted, and a high-pass filter to which the output of the low-pass filter is supplied are provided to extract signals being analyzed having frequencies higher than the cut-off frequency of the low-pass filter and lower than the cut-off frequency of the high-pass filter; the signals being analyzed are sampled; and data signals on the signals being analyzed for every predetermined time span are supplied to a personal computer; the personal computer extracting from the data signals signal components for each of a plurality of frequency components by means of a plurality of digital filters, and visually displaying the signal components for each of the extracted frequency components.
