ABSTRACT:
An input signal processor used in the control apparatus for an internal combustion engine of automobiles, the apparatus being equipped with an electronic computer, wherein the ripple components contained in a signal sampled with a constant period, e.g. a signal representing the air flow rate and the rotational speed of the engine, are eliminated through a predetermined arithmetic process by the use of an unprocessed signal x.sub.i at an instant t.sub.i and the signal y.sub.i-1 already processed at the instant t.sub.i-1 so that an optimal control of the internal combustion engine matched to all driving conditions of the automobile can be performed by using the processed signal without any ripple component.
