Biosignal-detecting apparatus and method thereof

摘要

A method of detecting a biosignal includes; measuring a biosignal from a user; band pass filtering the biosignal to each of a first frequency band and/or a second frequency band, and detecting a first frequency band signal and/or a second frequency band signal; calculating a PSD of the first frequency band signal and detecting a frequency band signal with a maximum PSD in the first frequency band as a heartbeat signal of the user; and calculating a PSD of the second frequency band signal and/or detecting a frequency band signal with a maximum PSD in the second frequency band as a respiration signal of the user.
