Abstract
A method for extracting peak information from an amplitude varying sinusoidal waveform output from a sensor is provided. The method includes gating a counter with a keying signal having a keying-signal period generated by a sinusoidal waveform associated with the amplitude varying sinusoidal waveform, receiving high frequency clock signals at the gated counter during keying-signal periods, wherein a clock-signal period is much less than the keying-signal periods, disabling the counter at the end of each keying-signal period, generating a quarter-count value based on the disabling, and outputting a sample pulse associated with each keying-signal period. If a current-keying-signal period is the same as a last-keying-signal period, the sample pulse is generated at a quarter-wave of the sinusoidal waveform. If the current-keying-signal period differs from the last-keying-signal period, the associated output sample pulses are adjusted to the quarter-wave of the sinusoidal waveform in the next-keying-signal period.
