摘要
The trigger point detection circuit, for a noise laden source signal, uses a pair of comparators for comparison of the source signal with respective variable threshold levels, their outputs controlling a counter which records the interval between the two threshold values being attained. The defined trigger points are indicated when the source signal exceeds a second threshold shortly after passing a first threshold with the second threshold raised when the source signal drops back below the first threshold before reaching a third higher threshold.
