Analog short-time interval converter on integrated circuits

Described is a converter of short time intervals into intervals of a larger duration. The converter is intended for simultaneous operation with a prompt time coder. A cable delay line determines duration of the maximum converted interval ranging from 50 up to 300 nsec. Duration conversion factor is 100. Differential non-linearity is +-1% with a channnel being 50 picoseconds wide. The converter is made with integrated circuits of K137 and K138 series
