In this paper, synthesis of shift counter based on the principle of feedback shift register by means of binary periodic sequence generation is discussed. Feedback functions are derived, by means of which the shift counters with variable phase shift, variable pulse width and variable frequency-division coefficient can be produced. The author used the method of state-transition transformation to prove that with such feedback functions the shift counters are capable of generating the desired binary periodic sequence, and that they have self-starting ability because their state diagrams, show only one cycle with branches. The method of sequence combination is also discussed, and it is pointed out that this method is very suitable for generating pulse trains having two or more pulse durations simultaneously.
