Abstract
Abstract An improved device for measuring the time of occurrence of a pulse centroid, particularly for irregularly shaped electrical pulses. An electrical pulse is fed to a first integrator whose output is fed to a summing network and a second inverting integrator. The output from the second integrator is also fed to the summing network. The output of the summing network is then fed to a zero crossing detector which provides an output related in time to the time of occurrence of the pulse centroid.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
74 words
An apparatus for providing an indication of the time occurance of a pulse centroid comprising: first integrating means for receiving an electrical input pulse and providing an integrated first output of said pulse; inverting integrating means for receiving said first output and providing an inverted integrated second output; means for summing said first and second outputs; and mean for detecting the time occurrence of the zero crossing of said summed first and second outputs.
Claim 2
Independent Claim
74 words
An apparatus for providing an indication of the time occurance of a pulse centroid comprising: first integrating means for receiving an electrical input pulse and providing an integrated first output of said pulse; inverting integrating means for receiving said first output and providing an inverted integrated second output; means for summing said first and second outputs; and mean for detecting the time occurrence of the zero crossing of said summed first and second outputs.
Claim 3
Dependent Claim
25 words
The apparatus of claim 1 further including means for setting the outputs of each integrating means to zero after the completion of each input pulse.
Claim 4
Dependent Claim
14 words
The apparatus of claim 1 wherein said first integrating means comprises an inverting integrator.
