6. How many 2-input NOR gates are needed to perform 2-input NAND operation? (a) 1 (b) 2 (c) 3 (d) 4 (e) 5 7. If both inputs of a 2-input gate are HIGH, the output is HIGH what gate could be this? (a) AND (b) OR (c) EX-NOR (d) a and b (e) all of the above 8. If both inputs of a 2-input gate are LOW, the output is LOW what gate could be this? (a) NAND (b) NOR (c) EX-OR (d) a and c (e) b and c 9. If two inputs have the opposite logic level, the output is HIGH what gate could be? (a) NAND (b) NOR (c) EX-OR (d) a and b (e) a and c 10. If two inputs have the opposite logic level, the output is LOW what gate could be? (a) AND (b) OR (c) EX-NOR (d) a and c (e) b and c
