Abstract:
A frequency divider operating in cascaded decades with selection switches adjustable for selecting from each decade the desired control signal and a gating network for combining the outputs of the respective decade switches for producing a time uniform divided pulse sequence.
Abstract:
A FREQUENCY DIVIDER FOR PROVIDING DESIRED SEQUENCES OF PULSES FROM A SERIES OF INPUT PULSES BY DECADE SELECTION SWITCHES PROVIDING THE DESIRED CONTROL SEQUENCE AND THE SEQUENCE INCREASED BY ONE AND A GATING CIRCUIT RESPONSIVE TO EACH CONTROL SEQUENCE AND CONTROL SEQUENCE INCREASED BY ONE FOR COMBINING EACH OF THE SEQUENCES INTO A SINGLE DESIRED FREQUENCY OUTPUT.

To synchronize input pulses at terminal E with clock pulses fed to a tri-stable device D, each input pulse is fed to the second stage of the device D so that on the occurrence of a clock pulse the second stage output is enabled to apply an enabling signal to AND gate G which passes a signal to the first stage when the input pulse terminates. When the next clock pulse occurs the first stage output is enabled to pass a pulse to terminal a and also to the third stage of the device D so that the system is returned to its rest position by the following clock pulse.
Abstract:
A ratio circuit for providing fine ratio control between a measured value and a desired value at a predetermined instant is provided with a comparison counter accumulating a measured value, and a plurality of selection devices each preset to a fractional proportion of the desired value. The presetting devices are driven by a common pulse source, all but the first presetting device coupled to the source via a frequency divider.
