Abstract
A programmable digital frequency divider comprises a programmable binary counter in receipt of an input pulse train to develop output pulses at a frequency variable as a function of a set of binary program control signals supplied in the form of normal binary number system. A binary code converter is provided to convert the binary number system of the program control signal into a modified binary number system in which the modified binary number is an integral multiple of the corresponding input binary number minus error compensating binary digits, wherein the number of compensating bits differs depending on the particular binary number. Electrical signals representing the modified binary numbers are supplied to the program input terminals of the binary counter so that the frequency of its output signal is substantially linearly variable as a function of discrete variations of the program control signal.
