VARIABLE CLOCK TIMING SYSTEM

摘要

PURPOSE:To give a timing command with the required accuracy of time and in accordance with the required time control band, by generating the division factor of an optional value in the real time variably against the basic frequency of the clock signal. CONSTITUTION:The coded control signal S(n) and the preset signal PS are delivered from the control device 30 in order to designate the division factor (n) and to set the time band for time control of the control subject 32 to the timer groups TM1-TMm respectively. Thus the control times T1, T2 and T3 are set to the timers TM1, TM2 and TM3 each by the signal PS. Then the clock signal C(f) the frequency of which is varied based on the signal S(n) delivered from the device 30 is taken in with the control time set to the timers TM1, TM2 and TM3 each, and the timing command based on the signal C(f) is given to the control subject 32. In such way, a timing command can be given with the time accuracy that is required in accordance with the required time control band.
