Abstract
An adjustable alternating signal having a desired period, P, is applied to a cycle counter arranged to count n cycles and applied to a timer arranged to time out n.multidot.P after a first cycle is applied to the counter and timer. A comparator is coupled to the counter and timer to determine whether the counter reaches its count of n cycles first or whether the timer times out first indicating that the period of the alternating signal is shorter or longer, respectively, than desired. An integrator is responsive to the signal from the comparator for changing the alternating signal which achieves the desired period.
