Abstract

PURPOSE:To obtain the time square function with a simple circuit constitution, by applying the output of the 1st counter to the 2nd and 3rd counters and supplying the output of the 2nd counter as the preset input of the 1st counter. CONSTITUTION:The n-th time interval of the output pulse of the output 11 of the counter 1 is Tn=N.h-Dn-1, where N is the total count of the pulse of the counter 1, (h) is the period of the clock pulse, and Dn-1 is the (n-1)th data inputted to the counter 1 as the preset data by the output of the counter 2. Further, the counter 1 is preset as 2an by the output 21 of the counter 2. Then, the relation of the time interval between the n-th and (n-1)th at the counter 1 is Tn=Tn-1-2an, where (a) is a constant. That is Tn-1-Tn=2an, resulting that the storage of the input digital signal in the counter 3 is made with the time square function.
