<P>PROBLEM TO BE SOLVED: To enable downsizing of a device determining a singular point of digital sampling data. <P>SOLUTION: A singular point determination device 10 is provided with: an FF 11 which delays and outputs an input signal G0; a subtractor 12 which outputs the difference between the input signal G0 and an output signal G1 from the FF 11; a comparison circuit 14 which compares an output signal D1 from the subtractor 12 with a threshold b1; an FF 13 which delays and outputs the output signal D1 from the subtractor 12; a comparison circuit 15 which compares an output signal D2 from an FF 13 with a threshold b2; and an AND circuit 16 which determines the presence or absence of the singular point of the input signal G0 in accordance with each comparison result of each comparison circuit 14 and 15. <P>COPYRIGHT: (C)2013,JPO&INPIT |
