VERFAHREN ZUM VERARBEITEN EINES ALS EINE FREQUENZ VORLIEGENDEN MESSWERTES.

摘要

An electrical signal is formed with the ratio of the measurement frequency to the reference. This electrical signal bears the same ratio to a given electrical reference. A step voltage is formed whose step number equals the frequency ratio and step height is derived from the given reference. The step height bears a fixed relationship to the electrical reference. The start of the steps and their end are defined by a time period derived from the mains frequency. The time point for the beginning and end of the steps is the mains voltage passage through zero.
