ABSTRACT:
A digital signal obtained by A/D converting an output of a thermal type air flow meter is supplied along two paths. After a time constant is obtained in one path, inverse-transformation is performed to obtain an error together with an output of the other path. The inverse-transformed signal is linearized on the basis of the characteristic of the thermal type air flow meter, and a direction of flow is determined.
