Worksheet: NOT Gates

In this worksheet, we will practice determining the input and output of NOT gates in logic circuits and completing truth tables for NOT gates.

Q1:

The diagram shows three NOT gates connected as part of a logic circuit. If the input is 1, what is the output?

Q2:

The diagram shows a NOT gate. If the input is 0, what will the output be?

Q3:

Which of the following symbols represents a NOT gate?

  • A
  • B
  • C
  • D

Q4:

The diagram shows a NOT gate. If the output is 0, what must the input be?

  • A0
  • B1

Q5:

Input 0 1
Output 𝑝 𝑞

The diagram shows three NOT gates connected as part of a logic circuit. The truth table shows the two different possible inputs.

What is the value of 𝑝 in the table?

  • A1
  • B0

What is the value of 𝑞 in the table?

  • A0
  • B1
