1. A method for a pulsation correction of a measured value of a flow measuring device, comprising: detecting a pulsating gas flow in an internal combustion engine; feeding a raw signal to an adder of a compensation circuit; feeding the raw signal to a multiple frequency filter to produce a filtered signal, the multiple frequency filter including at least one high-pass filter, at least one low-pass filter, and at least one band-pass filter; writing the filtered signal into an address of a correction characteristics map; and adding a values stored in the address to the raw signal by the adder.
