    摘要: A device control circuit is disclosed which includes the provision of control commands at precise time intervals by gating each command at a time controlled by a continuously running counter to which is added the next event delay value. Upon reaching a predetermined fixed value the next event gating signal is generated. The delay value may be entered at any time prior to the elaspe of the delay time and all gating signals are accurately time related with regard to a fixed reference and to one another.
