     I need to build a filter that will pass only 200ns or shorter
pulses found in a video signal.  (These pulses appear because the
video signal comes from a camera looking at a scene which contains
a laser beam.)  Any suggestions as to standard ICs which implement
a suitable filter with minimal parts count and few if any screwdriver
adjustments?
