Abstract

667,481. Pulse shaping circuits. TELEFONAKTIEBOLAGET L. M. ERICSSON. March 3, 1950 [March 3, 1949], No. 5438/60. Drawings to Specification. Class 40 (vi). A shortened pulse of predetermined duration is produced from an input pulse by applying the input pulse directly and via a delay network to the grid and cathode respectively of a valve so that an output pulse is obtained having a duration which is a function of the difference in transit time of the two input paths.
