<p>A pulse detector (100, 200) has a leading edge detector and a trailing edge detector. A timing circuit (300) is provided for determining the pulse duration between the leading edge and the trailing edge of a signal pulse; and a divider (170) divides the pulse duration to produce a first timing pulse representative of a mid-point or peak of the signal pulse. An inventer (210) may also be provided to produce a second timing pulse representative of troughs between signal pulses. A combiner (410) may optionally be provided for combining the first and second timing pulses. The detector has application in signal cleaning circuits.</p> |
