Abstract
Abstract An analog signal representing a continuously measured value is distributed to a plurality of capacitors, by a cyclic closing of a first set of contacts. The signal stored on the capacitors are read out by cyclic closing of another set of contacts which connect the capacitors to a receiver station. Each value of analog signal is delayed by the time interval between the storing in the capacitor and the read out from the same capacitor which occurs during the same cycle.
