The present invention discloses a biological signal processing method for measuring the physiological characteristics of the organism. Biological signal processing method according to the present invention has a different wavelength bands from each other, of the two signals function indicating a physiological characteristic of the living body, one of the signal functions P 1 (t differential P 1 against) (t) the other one of the signal function P 2 (differential P with respect to t) 2 and (t) divided by (a) step, and, following the following function n 1 using the Equation 1> < of constant b and the function of s (t) 1 (t) to win the period (b) I comprising the step. [1] in (the , P 1 (t) = s 1 (t) + n 1 (t ), P 2 (t) = s 2 (t) + n 2 (t), as 1 ( t) = s 2 (t), bn 1 (t) = n 2 (t), a, b, and k is a constant , variable t is time, n 1 (t) and n 2 (t) are each signal function due to noise (Noise) at the time of the biological signal measurement) According to the present invention, it is possible to extract the desired data in the user, ie, a signal period of the data which the noise component is removed through a simple process, a process that required for the detection of physiological characteristics is it can be simplified.本発明は生体の生理的特性を測定するための生体信号処理方法を開示する。本発明に係る生体信号処理方法は、互いに異なる波長帯域を有し、上記生体の生理的特性を示す2つの信号関数のうち、いずれか1つの信号関数P1(t)に対する微分P1(t)を他の1つの信号関数P2(t)に対する微分P2(t)で割る(a)ステップ、そして、下記<数式1>を用いて下記関数n1(t)の定数bと上記関数s1(t)の周期を獲得する(b)ステップを含んでなる 。【数1】(上記<数式1>で、P1(t)=s1(t)+n1(t)、P2(t)=s2(t)+n2(t)、as1(t)=s2(t)、bn1(t)=n2(t)、a、b、及びkは定数、変数tは時間、n1(t)とn2(t)は各々生体信号測定時のノイズ(Noise)による信号関数である)本発明によれば、ユーザの所望のデータ、即ちノイズ成分が除去されたデータの信号周期を簡単な処理過程を通じて抽出することができるので、生理的特性の検出のために必要とする過程が簡略化できる。
