  "textContent": "The invention relates to a method and a device for pulsation correction of an output signal of an air mass sensor for air mass detection of combustion air of a supercharged internal combustion engine. The method is characterized in that a first correction factor (10) and a second correction factor (18) are used to correct the output signal of the air mass sensor for pulsation effects. The first correction factor (10) is determined as a function of an output signal of the air mass sensor (1) and of a compression ratio (8) of a compressor of an exhaust gas turbocharger, and the second correction factor (18) is determined as a function of a calculated exhaust gas mass flow (14) and of an expansion ratio (16) of a turbine of an exhaust gas turbocharger.",
