an OR gate produces a 0 output only if its two input values are 0 an AND gate and an OR gate produce opposite output the inversion bubble of an AND gate causes its input to be reversed a gate is a device that accepts a single input signal and produces one or more output signals a NOT gate allows only one of its two input values to pas

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.

2. Design a logic circuit with two inputs and 4 outputs, with each of the outputs hooked up to an LED. Only the first LED should light up when the input values are 00. Only the next LED should light up with the input values are 01. Only the following LED should light up for 10, and only the last LED should light up for input 11. Thus for each input combination, you should have one LED only being lit. This is called a DECODER circuit, you are decoding 2 bit binary input to one of 4 discrete outputs. a. Create the truth table (use the standard truth table format). b. Write a Boolean expression that corresponds to the truth table.

Exclusive-OR (XOR) logic gates can be constructed from what other logic gates? Select one: a. OR gates only b. AND gates and NOT gates c. OR gates and NOT gates d. AND gates, OR gates, and NOT gates

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

The output of an OR gate is LOW when(a) any input is HIGH             (b) all inputs are HIGH(c) no inputs are HIGH          (d) Both (a) and (b)

Write the Boolean expression for a four-input NOR gate. F(A, B, C, D) =
