boolean Logic
Cards in this deck (7)
- 1how to construct truth table from circuit diagram?start by making a column for every input on the left, (EVERY PRIMARY INPUT preconstructed)
depending on how many bits for the individual letters (see what all 1s would amount to in denary and then the number of outcomes is 0 to that number)
make more columns for junction inputs and outcome column last
then the FINAL output which will be one of the combinations
(label every line)
make all junctions inputs into a formalu state - 2what to make sure of when constructing truth table from scenario?consider every input including methods to stop result. write everything out as Letters when it comes to truth table
- 3how to make a 2 INPUT karnuagh mapdraw out table
put one variable along the top and the other along the side
enter both possible states for each variable below or beside
SEPERATE EXPRESSION ON THE OR SYMBOL - 4HOW TO MAKE A 3 INPUT KARNAUGH MAP?SAME AS 2 INPUT BUT PUT TWO INPUTS ACROSS TOP AND ONE INPUT ACROSS BOTTOM THEN WRITE OUT ALL POSSIBLE STATES
- 5WHAT IS THE RULE FOR KARNAUGH MAPWHEN WRITING OUT THE OUTCOMES OF THE KARNAUGH MAPS, ONE VARIABLE HAS TO CHANGE STATE PER BOX, CANT HAVE TWO VARIABLE CHANGES IN ONE BOX
- 6DE morgans equivalent laws-(A^B) = -A v -B
-(A v B) = -A ^ -B
ANY LETTER ^ 0 is 0
ANY LETTER ^ 1 is the LETTER - 7what is distribution law?the rule that explains how expressions are expanded.
OR: a^(b v c) = (A and B) OR (A and C)
for AND: a v (b^c) = A or B and A or C
