Abstract

PURPOSE:To decrease the quantity of operation and to output a correlation function having a high accuracy, by inputting a signal represented by the latest correlation functon from a short time correlation function computer, operating an updated correlation function, and storing the latest correlation function. CONSTITUTION:Analog signals X<1>-XM are quantized at every constant time by an A/D converter 1, and its quantized data is stored in the first data memory device 6. Also, the quantized data outputted from the device 6, and a signal representing the number of time lag from the second setting device 5 are inputted to the first operator 8, and a short time correlation function of every quantized data is calculated at every constant time. A correlation function from this operator 1 is stored in the second data memory device 9, and a signal from this device 9 and a signal representing the latest correlation function from the device 6 are inputted to the second operator 11, and an updated correlation function is operated. An updated correlation function calculated by this operator 11 is stored in the third data memory device 10, and an output of the device 10 is outputted as a correlation function to the next stage.
