in thread Bit operations for beginners

I used a chart like yours too for a while. After the instructor completed Boolean algebra and tested us on it, we weren't required to use it any more. At that point Karnaugh maps became my good friend! I guess that marks me as an engineer...

Like you I order my chart as a mathematician, engineer or programmer would ...

I found the following counting method most useful as it worked best with K-maps. In fact, this is the table I sketched into the front cover of my digital circuits textbook :)

A | B | A or B | A nor B | A xor B | A and B | A nand B |

0 | 0 | 0 | 1 | 0 | 0 | 1 |

0 | 1 | 1 | 0 | 1 | 0 | 1 |

1 | 1 | 1 | 0 | 0 | 1 | 0 |

1 | 0 | 1 | 0 | 1 | 0 | 1 |

Cheers,

Brent
