What is the difference between predicate and propositional logic?

in propositional logic a complete sentence can be presented as an atomic proposition. and complex sentences can be created using AND, OR, and other operators.....these propositions has only true of false values and we can use truth tables to define them... like book is on the table....this is a single proposition... in predicate logic there are objects, properties, functions (relations) are involved.


What are tables of logic?

A table of logic, or truth table, lists the possible combination of truth values for boolean (logical, two-valued) variables.


What is a table organizing the input rule and the output of a function?

If it is boolean logic, typically that is called a Truth Table.


What is the difference between two logic equations being equal versus two logic equations being equivalent?

Equal is the truth table and the circuit are the same. Equivalent is when the truth table is the same but the circuit is different


How do you get the output of a three input truth table A B C?

by analyzing your three input logic network


Find the logic expession and the truth table of the logic function F realized by the following cicuit?

It would be very nice to see the following circuit.. :P


Is Digital design often starts by constructing a truth table?

No, digital design does not always start with constructing a truth table. While truth tables are a common visualization tool for understanding logic circuits, digital design can begin with various methods such as designing the logic diagram or state diagram. Truth tables are typically used after the design stage to verify the functionality of the digital circuit.


How do you get the output of a three input binary truth table A B C?

Does propositional calculus take truth values to be the most basic element of logical analysis?

Yes.


A nand gate becomes gate when used with negative logic?

negative logic means negative input values. so by checking the truth table, it becomes an OR gate


What is classical logic and multivalued logic?

Classical Logic allows two truth values, True and False. Multivalued or "many-valued logic" allows other kinds of truth values and it allows there to be more than two truth values.


Define a truth table?

A truth table is usually a table in which the truth or falsehood of two variables are taken as input and these form the edges of the table. The content of the table shows the truth value of the result of some operation on the variables.
