The Generator of Average and Major Time Intervals of High Accuracy for On-Off Objects Control

The single-channel line driver of average and major time intervals of high accuracy (FTI) on the basis of the known method of summation of single temporal increments is developed. Increase in time interval accuracy is provided due to value reduction of the instrument dynamic error which always arises at the time of front (end, edge) time interval formation. Reduction of an instrumental dynamic uncertainty is provided by simplification of the canal of program time codes conversion of the known FTI structure to fronts of time intervals. Formation of the high accuracy time interval front is executed in two stages. At the first stage, the program code of time В from the RAM outputs proceeds to the canal of preliminary conversion where its value decreases on 1. Then comparison of the received B-1 code with a real code of time A, proceeded from outputs of the real time counter is executed in the unit of the codes comparison circuit (CCC). In case of equality of the B-1 and A codes, the received result of comparison from an output of the unit CCC is recorded in the T-trigger. At the second stage the next program pulse of the generator proceeds simultaneously on the preliminary conversion canal input and to a time intervals fronts formation path on a dynamic input of D-trigger synchronization. At this moment copying of the kept result of comparison from the T-trigger to the D-trigger with simultaneous D-trigger state change is executed, i.e. formation of the real time interval program front on an FVI output corresponding to a B=A+1 program time code. Pulse "Start-up" of FVI marks the beginning of formation of time intervals.
