PURPOSE:To enable a measurement processing with a circuit having a number of common parts by sampling at least original information on revolutions of the engine and original information for display of acceleration from a single information signal or a sensor as the same original information. CONSTITUTION:A ignition timing signal Si of the internal combustion engine for a vehicle is inputted into an input terminal In from an ignition timing signal detecting section 2. When this signal Si is inputted into an frequency-voltage conversion circuit 3, the output Svo thereof varies in the voltage in proportion to the revolutions of the internal combustion engine. When this output Svo is inputted into an acceleration computation circuit 4 to compute the variation rate thereof, the output Sa thereof appears at an output terminal O1 as bearing acceleration information transformed in voltage. On the other hand, the output Svo of the circuit 3 can be sent as output signal Sr having the revolutions of the engine transformed in voltage by introducing to an output terminal O2. Signals Sa and Sr developed at the terminals O1 and O2 are processed with displays Da and Dr to be indicated on a operating vehicle. |
