ABSTRACT:
An FM demodulator wherein the input signal excursions advance a counter. At each of a sequence of equal sample times, the count is compared to a value which is the average of the highest and lowest counts during the sequence. The comparison may be numerically direct or by down-counting from a present number. The result of the comparison sets an output data value either "1" or "0".
