  • Frequency divider
    Patent number: 4704723
    Abstract: A method and apparatus for dividing a clock pulse frequency Cl in a ratio A/B, where the quotient between B and A is the whole number C and the remainder D. A pulse train is generated, which includes (A-D) half pulses with a pulse length of C clock pulses and also includes D half pulses with a length of (C+1) clock pulse lengths. The difference between C and (C+1) is the deviation in pulse length of the divided clock pulse frequency.
