a) Light in a two-story building is controlled by two switches. The top switch is labeled Sj and bottom one is labeled S2. When a switch is “ON" the value is “1" and when a switch is “OFF" the value is “0" The light goes "OFF" when both switches are "ON" or both are "OFF". Draw the Truth Table of the lighting system. Write down the logic equation of the system in a SOP form Implement the circuit of the lighting system using the SOP logic equation in (b) using AND-OR gates
A chemical process takes place in a reactor vessel continuously, but it has to be monitored for abnormal behaviour. The system has two sensors S1 and S2 that can independently detect an abnormal temperature. They pass an electrical signal to an electrical OR-gate A, which passes a signal on to both the protection units P1 and P2 if either sensor gives a signal. The protection units and the OR-gate get electrical power from electric power unit E1, while sensors get power from electric power unit E2. Build a (qualitative) fault tree for the top event "Protection system not available" using failure of the indicated components.
6-22 A sequential circuit has three flip-flops, A, B, C; one input, x; and one output, y. The sta diagram is shown in Fig. P6-22. The circuit is to be designed by treating the unused stat as don't-care conditions. The final circuit must be analyzed to ensure that it is sel correcting. (a) Use D flip-flops in the design.

The beginning of the program is provided in Figure 4. #include void main () //variable declaration int S1, s2; //read input values printf ("\nEnter values for S1 and S2 (0 or 1): "); scanf ("&d %d",&S1,&S2); Figure 4
1. An ocean front restaurant has purchased several automatic windows, which are designed to close whenever they receive a logic'1'. The restaurant wants the windows to close when it's either cold(c-1) or both windy(w=1) and raining(r=1). Create a simple digital circuit which determines when the windows should be closed using only two gates. Suppose a technician hired by the restaurant designed the following Boolean expression: (r'+c)'w+c . Using Boolean algebra, prove that both expressions implement the same function("are equivalent"). . Which expression would you use in the final design? Why? 2.
