ABSTRACT:
A circuit arrangement for linearizing the output signal of a probe such as a hot-wire probe used for quantitative air measurement in the intake manifold of an internal combustion engine which includes a log stage, a multiplier stage and an antilog stage connected in series, the probe signal being applied to the input of the log stage and the linearized output signal taken from the output of the antilog stage.
