  • Device for measuring a pulsating variable in an internal combustion engine
    Patent number: 5069063
    Abstract: A device for detecting a pulsating variable by fixed-angle dual sampling with slight filtering in which the pulsating variable is filtered and/or damped in such a manner that a quasi-sinusoidal variation is obtained. The signal thus obtained is a crank-angle-synchronous signal sampled twice per duration of one period. From these two measurement values, a current mean value of the pulsating variable is determined once per duration of the period.
