Abstract
A circuit for generating two clock pulse trains of opposite polarity to one another each at a frequency of a single input clock pulse train including a flip-flop for providing the two output clock pulse trains, apparatus for placing the flip-flop in a first condition in response to the input clock pulse train, apparatus for producing signals for placing the flip flop in a second condition in response to the input clock pulse train after a first delay, apparatus for producing signals after a second delay in response to the first delayed signals, apparatus for equating the delays so that the first half of each clock pulse is the same length as the second half, and apparatus for comparing the input pulse train to the pulse trains produced to increase the frequency of the output trains produced responsive to the detection of a subharmonic of the input frequency.
