  • Simplified frequency to digital converter using all digital electronics
    Patent number: 4144489
    Abstract: An all digital circuit converts a signal of an unknown frequency into an accurate binary representation of that frequency. The apparatus consists of an all digital closed loop system which has as its input the unknown signal. The closed loop system generates a reference signal and forces the frequency thereof to approximate that of the unknown signal. In so doing, the closed loop generates a binary number representative of the frequency of the reference signal and provides this number as the system output.
