ABSTRACT:
In a crank angle sensor signal processor including a microcomputer, the number of generated unit crank angle (1.degree.) signals are counted and compared with a predetermined level. An interrupt demand signal is generated in response to a reference signal only when the number of generated unit signals exceeds the predetermined level in order to minimize the effects of noise on the reference signal. The reference signal is expected to be inputted to the processor immediately after the number of generated unit sensor signals exceeds the predetermined level.
