2091349 9204634 PCTABS00011 A dual-edge frequency counter and method for minimizing the effects of duty cycle modulation. In its simplest form, a dual-edge counter (50) includes a first counter (52) that accumulates reference clock pulses between successive rising edges of an input signal. An input signal is also applied to an inverter (54), which inverts the square wave signal prior to applying it to a second counter (56) that also accumulates reference clock cycles between successive rising edges of the inverted sensor signal. A summation junction (60) totals the accumulated counts from the first and second counters so that they can be averaged by a divider (62), which divides the total count by two. The technique is also employed in connection with a frequency counter that includes an integer counter (72) for totaling the number of cycles of the sensor signal occurring during a sample time defined by successive gate signals.
