Logical Statements VS Digital Logic
« on: July 29, 2009, 10:06 PM »

I'm taking a class called digital state machaines and this have statements that are combined with AND, OR, IF, IF AND ONLY IF, etc. and needs to make truth tables.
Does these truth tables follow the same pattern as a digital logic truth table will follow? If so what is equal to what? (true = 0 or true = 1)?
Thanks

Yes the basics are pretty much the same. true = 1 and false = 0. when you are creating the truth tables instead of starting from 0  0  0 you starts with T   T   T and goes backwards. Pretty much a digital logic 1 and 0 truth table written from bottom up.
A 3 variable truth table will look as follow:

x   y    z
T   T   T
T   T   F
T   F   T
T   F   F
F   T   T
F   T   F
F   F   T
F   F   F

Guess this will be helpful enough. There are some more attachments on this subject on the other posts. Take a quick look on them.
