On a negative going transient at input (A), a negative
pulse at C will turn “on” the CA3094, and the output (E)
will go from a low to a high level.
At the end of the time constant determined by C

, the CA3094 will return to the “off” state and the
output will be pulled low by R

. This condition will
be independent of the interval when input (A) returns
to a high level.
