Questions tagged [truthtable]

A truth table is a mathematical table used in logic—specifically in connection with Boolean algebra, boolean functions, and propositional calculus—to compute the functional values of logical expressions on each of their functional arguments, that is, on each combination of values taken by their logical variables.

In particular, truth tables can be used to tell whether a propositional expression is true for all legitimate input values, that is, logically valid.

Practically, a truth table is composed of one column for each input variable (for example, A and B), and one final column for all of the possible results of the logical operation that the table is meant to represent (for example, A XOR B). Each row of the truth table therefore contains one possible configuration of the input variables (for instance, A=true B=false), and the result of the operation for those values.

Implement a function using Boolean Circuit

I need to implement some multi-variable function in a Boolean Circuit; what tools do we have in order to automatically convert some arithmetics into a boolean circuit? For instance, part of the formula I want to implement is the operator max(a,b)…

Why bitshift when evaluating truth tables as binary numbers?

The last answer in this question shows that a binary truth table can be represented as a binary number: 0 0 0 | 1 0 0 1 | 1 0 1 0 | 0 0 1 1 | 0 1 0 0 | 1 1 0 1 | 0 1 1 0 | 1 1 1 1 | 0 Can be represented by 01010011. The entries in the…

Splitting a string based on specific characters

I will try to describe my problem as well as I can. I am trying to write a program that will handle equations like: F = (X∨A) ↔ (X∨B) ( (X OR A) is equivalent to (X OR B) )! I have to solve it by 'X', or to better say, write disjunctive and/or…

Circuit design that outputs square of binary input

So for my digital logic course, we were asked to design a combinational circuit with 3 inputs, and an output that generates the square of the binary input. I assume she means the inputs are 3 bit binary numbers 0-7. In describing the solution, she…

Java Truth Table Stack - Pop only returning last calculated value?

I'm having trouble phrasing my question correctly, so bear with me. It may be better to give an example. Here's what I get when I run for P&Q&R PQR: TTT = T FFF = F TTF = F FFT = T TFF = F FTT = T TFT = T FTF = F It's just looking at R and taking…

Reading logical operators expression for truth table C++

I am trying to write a code that will take an expression that is formatted similar to (((p∨q)∧((q→r)⊕(p∧r)))↔(r∧q))→(p∨r) and it needs to print out the truth table for it which looks something like p q r (p V q) (q→r) etc... until it gets to…

Is my truth table for this Logic Circuit correct?

How would I make a truth table for this Logic Circuit My attempt: I think the logic expression would be along the lines of: Z= −(−(A∧B)∨−(A∧B)∧−(B∧C))∧(−(A∧B)∧−(B∨C))

Truth Table For Switching Functions

Can someone explain how these concept works? I have 1 question. But I don't know have any ideas on constructing the truth table. f(A,B,C) = AB + A’C The answer given was ABC + ABC' + A'BC + A'B'C And i have no idea how it get there. :-(
