Question

How do you draw a circuit for this method? Thanks

Your task will be to design digital logic circuits that accept input signals {S1, S2, S3, S4} and produce output signals {C1, C2, C3, C4} according to certain design specifications. Method 1 This circuit should produce Ck = Sk (k=1 through 4), with the following exception: As an automobile crosses the boundary between adjacent car wash areas, it is possible that two sensors are simultaneously activated. To prevent any interference between different washing operations, turn off all car wash functions {make C1 = C2 = C3 = C4 = 0} whenever any two adjacent sensor outputs are high.

Answer 1

Truth table for method 1

S4 , S3 , S2 ,S0 are inputs from sensors

C4 ,C3 ,C2 ,C1 are outputs
