Abstract

PURPOSE:To set a threshold value by using yp, which satisfies integral (ypinfinity P(y) dy)=C provided that C is a constant depending upon features of a probability density function of a noise and P(y) is a probability density function of the value of data, found from a string of observation data. CONSTITUTION:An observation value obtained by sensor 1 is amplified by amplifier 2 before being inputted to information extracting circuit 3. One extracted observation value output is inputted as it is to comparing circuit 6 and the other to yp calculating circuit 4 providing yp calculation. Then, yp is found and inputted to K- multiplying circuit 5 for determining threshold value TH=Kyp (K: constant). The output of K-multiplying circuit is threshold value TH, which is compared by comparing circuit 6 to the extracted observation value so as to decide the existence and magnitude of a signal.
