摘要: The invention discloses a method for automatically positioning and repairing clipping distortion waveforms of an electronic stethoscope. includes the following steps that: auscultation signal is read; difference x obtained, differential obtained; through threshold comparison endpoint pairing, K non-overlapping time intervals determined, are sorted in order, stack formed by entering first then exiting; if K=0, area avoided, no longer needed, K>=1, data point set psi interpolated on corresponding value x(psi ) at each used, anda Kth section fitted to replace original interpolation; interval top removed; without output. According stethoscope, stethoscope signals can be detected positioned, plurality close areas repaired.
