<P>PROBLEM TO BE SOLVED: To detect appropriate pass timing that does not depend on a method for reducing detection periods of pass timings. <P>SOLUTION: A pass-timing detection apparatus has an electric power addition means for calculating the electric power value, based on a voltage addition output calculated by adding voltage levels of a plurality of reverse-diffused samples and calculating the current electric power value at each timing; a pass timing selection means for selecting a pass timing from each timing; and a storage means for storing old pass timings that were selected in the past and old electric power values at the old pass timings. A partial electric power value, that is acquired by multiplying specified factor to the old electric power value, is added to an electric power value at the timing which is equal to the old pass timing. <P>COPYRIGHT: (C)2008,JPO&INPIT |
