1. A system for processing decaying periodic physiological signals including:
- at least a sensor, for sensing the decaying periodic physiological signals of a human body;
a physiological signal-digitizing device, for receiving and digitizing the decaying periodic physiological signals; and
a digital signals processing unit, for digitalizing and decomposing decaying periodic physiological signals D of the human body into poles P and residuals S, wherein the poles P represent the decay rate of signals, the residuals S represent the contribution value of the P, and by taking j as the serial number of signals, Dj represent periodic signals with different characters, or the same periodic signals in different measuring time or locations, and Dj, P and S satisfy the following formula;
wherein m represents the maximum number of poles from the decaying periodic physiological signals to be decomposed and is collected from a human body, Pji represents the ith pole of the jth periodic human signals or jth location of the sensor, and Sji represents the contribution value or residual value of the pole;
thus, obtaining the values of the poles Pji and residuals Sji by decomposing the decaying periodic physiological signals by using a numerical method.

Abstract
A system for processing decaying periodic physiological signals comprises at least a sensor, a physiological signal-digitizing device, and a digital signal processing unit to establish a parameterized database according to Pji, Sji, the relationship between Pji and Sji and the change with respect to time or locations of the sensors on the human body for evaluating the physiological or mental conditions. The system is applicable to processing and utilizing the decaying periodic physiological signals, such as heartbeats, respiration and ECG.
