ABSTRACT:
Circuit for generating a trigger pulse delayed within a period of a periodical motion of variable periodic time, the phase lag relative to a zero phase being dependent on the periodic time and other parameters, a zero pulse and angle pulses starting at zero 5 phase being generated, the pulse frequency being inversely proportional to the periodic time, the angle pulses being fed into a counter and correcting data being generated within every period during a constant-time window. The technical problem the invention relates to is to design the circuit so that a single sequence of angle pulses may be evaluated and no control pulses are necessary except a reference pulse for defining a reference phase. According to the invention the following solution to the problem is proposed: during a constant-time window the angle pulses are varied under control so that each single pulse may be duplicated, counted normally, or suppressed. In this way correcting pulses according to individual characteristics may be generated during the time window.
