Abstract
Rotational speed of a vehicle speed detecting gear 1 is detected by a detection element 2 using an MRE or the like and the detected signal is waveform-shaped by a waveform shaping circuit 3 to serve as a vehicle-speed pulse signal. The cycle of the vehicle-speed pulse signal is detected by a sampling circuit 4. The detected cycle of the pulse signal is multiplied by a predetermined multiplier in a multiplication circuit 6 and the multiplication result is divided by a predetermined divisor in a diving and pulsing circuit 8. Then, a pulse signal having the cycle equivalent to the division result is output as a divided vehicle-speed pulse signal.
