Question

Four digital outputs V, P, T and H monitor the speed v , tyre pressure p , temperature t and relative humidity h of a car. These outputs switch from 0 to 1, when the values of the parameters exceed 85kmhr,2bar,400C and 50% , respectively. A logic circuit that is used to switch ON a lamp at the output E is shown ahead.
