Abstract
Abstract 1. A pulse encoder comprising a set of series connected pulse producers, a multiple frequency source, said source being connected to the input of one of said producers the latter being controlled thereof, delay networks disposed in the series connections of said producers, a second set of pulse producers connected in parallel lines and driven by the output of the first mentioned set of producers, means for pulse position modulating the pulse generated by said second set of pulse producers, said means being controlled by said source and another of said producers, a common output line, each of said pulse producers in the two sets of producers being individually connected to said common output line, and a pulser connected to said output line.
