Title: Time measuring device
Inventor: KATANO KAZUYA
IPC: G04F10/04
Filed: 1992-02-28
Abstract: PURPOSE:To realize a time measuring device capable of accurately analyzing a signal regardless of the cycle of a sampling lock by providing a delay element means inputting the signal from a time width sampling signal generating circuit and delaying the inputted signal on the basis of the control from the outside and a delay element control means for controlling the delay element means. CONSTITUTION:A delay element 13 delays the signal inputted from a source clock generating circuit 11 on the basis of the number of data from a delay control means 12 and the output of the delay element 13 becomes a sampling lock. The delay control means 12 outputs data for delay to the delay element 13 at every cycle of the sample lock. For example, since d1 is outputted at the first cycle as shown by (b) in the delay control means 12, the signal inputted from a source clock (a) is delayed by the delay quantity due to d1 to become a sampling lock. This data is same in the case of d2 or d3. Therefore, the rising of a sampling becomes random and, as a result, the change of an input signal synchronizing to a sampling cycle can be measured.
