Gates question 1 - 7 = [44 pts - 7 points each] 1 Indicate which of the following logic gates can be used to realize all possible combinational Logic functions (a) OR gates only (b) NAND gates only (c) EX OR gates only (d) NOR gates only 2. A bulb in a staircases has two switches, one switch being at the ground floor and the other one at the first floor. The bulb can be turned ON and also can be turned OFF by and one of the switches irrespective of the state of the other switch. The logic of switching of the bulb resembles gate. 3. Describe the three notations used to describe the behavior of gates and circuits. 4. What is the relationship between the number of inputs a gate has and the size of the truth table that describes it. ? 5. The equation A(B+C) = (AB)+(AC) represents the of AND gates. property (or law)
