Question 6 |

Consider a parity check code with three data bits and four parity check bits. Three of the code words are 0101011, 1001101 and 1110001. Which of the following are also code words?

1. 0010111 2. 0110110 3. 1011010 4. 0111010

1 and 3 | |

1, 2 and 3 | |

2 and 4 | |

1, 2, 3 and 4 |

Question 6 Explanation:

Let x

Given transmitted codewords are

By inspection we can find the rule for generating each of the parity bits,

Now from above we can see that (I) and (III) are only codewords.

_{1}, x_{2}, x_{3}are data bits, and c_{1}, c_{2}, c_{3}and c_{4}are parity check bits.Given transmitted codewords are

By inspection we can find the rule for generating each of the parity bits,

Now from above we can see that (I) and (III) are only codewords.
