Which of the following statements is NOT correct about logic gates? Select one or more: The output of an XOR gate is 1 (HIGH) if the inputs complement each other If all inputs to an AND gate are 1 (HIGH), the output is 0 (LOW) A NOT gate can be used to produce the 1's complement of a binary number A NOR gate can be considered as an OR gate followed by a NOT gate

A) Draw a three-input OR gate, its Boolean expression, and its truth table. B) Repeat part (A) for a three-input NAND gate. C) Repeat part (A) for a three-input NOR gate.

6. Predict the output from each gate for the input variables shown: C A D B E Find out the values of C, D, E, F and G (show your calculation how you are getting the numbers) Input: A = 0 and B = 0 Find C, D. E, F, and G Each answer will be either 0 or 1

نه Construct the XOR operator using only AND, OR, and NOT gates. Construct the XOR operator using only NAND gates. Hint: xXOR y = (xy)(xy)
