# Worksheet: NOR Gates

In this worksheet, we will practice determining the input and output of NOR gates in logic circuits and completing truth tables for NOR gates.

**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?

- A(a)
- B(b)
- CNone
- D(d)
- E(c)

**Q6: **

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

NOR Gate | ||

Input A | Input B | Output |

0 | 0 | |

0 | 1 | |

1 | 0 | 0 |

1 | 1 | 0 |

What is the value of in the table?

What is the value of in the table?

**Q7: **

The diagram shows the circuit symbols for four logic gates. Which symbol represents a NOR gate?

- A(c)
- B(d)
- CNone
- D(b)
- E(a)
