Abstract

A device for detecting a pulsating variable, for instance the air flowing in the intake tube of an engine, is disclosed in which the signal processing and the correction of the pulsation error are done in an evaluation device which is a constituent of the sensor. At the output of the signal processor, the sensor, for instance a hot-film air flow rate meter, outputs a corrected output signal, which is directly a measure of the variable to be determined, such as the mass of the air flowing in the intake tube of an internal combustion engine.
