Dual modulus programmable counter

Abstract From the Canadian patent

The inventive counter is operable to divide an input signal by the sum of two binary numbers A and B. Each, number is stored in memory. These numbers are alternately preset into a binary counter which also receives the input signal. A logic gate monitors the counter output and changes state when the number previously preset in the counter equals the accumulated count. The gate state transition is used to preset the counter with the alternate stored number. Thus the process continues whereby the output from the logic gate represents the input signal divided by the sum of A and B.
