<p>Device for measuring a pulsating variable by fixed-angle double sampling with weak filtering. The pulsating variable is filtered and/or attenuated so as to obtain a virtually sinusoidal curve. The signal so obtained is sampled twice per period in synchronization with the crankshaft angle. The actual mean value of the pulsating variable is determined from these two measured values once per period in a control device.</p> |
