Abstract

Improvements in electronic devices for measuring the frequency of periodic electrical signals in which the duration of each individual period of the frequency to be measured is transformed into a voltage value proportional to the frequency, especially for use in protection devices against blocking or vehicle skidding, characterized in that said devices comprise connection elements to analyze the duration of each individual period of the frequency to be measured, electronic elements being provided to determine the reciprocal duration of the periods.
