In this lesson, we will learn how to determine the input and output of NOR gates in logic circuits and complete truth tables for NOR gates.

Q1:

The diagram shows 2 NOR gates connected as part of a logic circuit. Use a truth table to work out what type of logic gate this arrangement is equivalent to.

Q2:

The diagram shows 3 NOR gates, where the outputs of the first 2 NOR gates are the inputs to the third. If input A is 1, input B is 0, input C is 1, and input D is 1, what is the output?

Q3:

The diagram shows a NOR gate. If input π΄ is 0 and input π΅ is 1, what will the output be?

Q4:

The diagram shows a NOR gate. If input A is 0 and the output is 1, what must input B be?

Q5:

Which pair of logic gates shown in the diagram produces the same output as a NOR gate?

Q6:

The truth table shows the output of a NOR gate for various combinations of inputs.

What is the value of π in the table?

What is the value of π in the table?
