PURPOSE: To provide a generator of programmable time interval by which the accuracy can be improved in comparison with a conventional digital generator. CONSTITUTION: The time interval generating device comprises the first and second digital counters 1, 5 a memory 2, a digital divider 3, and a digital adding machine 4, the counting is started by the counter 1 when the first event is generated, then only. the digit of higher position of a figure of the counted number, is memorized when the second event is generated, thereby the dividing by the omission, is performed. At least two separate fractions are obtained from the memorized number by the divider 3, and the fractions are added by the adding machine 4 operated in the binary digit string. The counter 5 counts down the sum to generate a signal at the clearing. |
