Abstract
A pulse position detector responding to the leading and trailing edges of a pulse at a point where it crosses a threshold level. Responsive to the leading edge, a capacitor begins to charge with a characteristic which is represented by a slope of a first line. Responsive to the trailing edge of pulse, the capacitor begins to charge at a second rate which is represented by a second line having a slope which is twice the slope of the first line. An one-shot multivibrator responds to the change in the charge rate to measure a time period which depends upon the slopes of the two lines. That time period is substracted from a standard time period in order to indicate where the center of the pulse appeared.
