Abstract

A circuit for storing a multi-digit decimal numerical value of the distance traversed by a vehicle having a signal transmitter which gives off electric counting pulses, and particularly an electronic tachometer. The improvement consists of the numerical value being able to be stored by means for coding the numerical value in a one-step code for a non-volatile storage formed of floating-gate storage cells.
