摘要 |
First and second sample-hold circuits sample and hold the atmospheric pressure alternately every time when a vehicle travels a predetermined distance. A signal representing a difference between the holding values of the first and second sample-hold circuits, that is, a signal representing a slope of the road on which the vehicle is travelling is displayed through a latch circuit.
