Claims

[Scope of utility model registration request]

a distribution circuit for the pulse wave to be measured; a time measurement circuit for timing the pulse width of the output pulse wave of the distribution circuit; and an output of the time measurement circuit that is appropriately selected from among the time measurement circuit in conjunction with the distribution circuit. A device consisting of an output selection circuit that outputs a counted value, comprising three or more of the time-measuring circuits, the time-measuring circuits perform time-measuring operations in a fixed order, and the time-measuring circuit that is currently measuring time continues to perform the time-measuring operation until immediately before the time-measuring starts. A pulse wave period clocking device, characterized in that the pulse wave period clocking device outputs a counted value of the clocking circuit.
