Abstract

A circuit arrangement for adding, storing and reproducing electric counting pulses, is suggested, which preferably serves as an electronic kilometer counter of a motor vehicle with a distance transmitter (10). The circuit arrangement comprises an overwritable nonvolatile storage (16) which is divided into a series of storage registers (19) in which the counting pulses are stored by a one-unit shift code. When erroneous information occurs in any storage cell, the error of the indicated storage contents amounts to a maximum of .+-.1. This is achieved in that the control circuit (13), beginning with the first register (14), writes each new counting pulse into the next register (13, 12 . . . ) and, after reaching the last register (0), increases the contents of the first register and then the following respective registers by one unit with the next counting pulses. Such a circuit arrangement is to be used as a kilometer counter, operating time counter, quantity or piece counter, and the like.
