A truth table is a systematic way of representing all possible combinations of inputs and their corresponding outputs for a logical expression or digital circuit. It is widely used in Boolean algebra, digital circuits, computer programming, and mathematics to analyze and design logical expressions and circuits.
Constructing a 4-Input Truth Table
To construct a truth table for a logical expression with four input variables (A, B, C, and D), follow these steps:
Identify the input variables: In this case, the input variables are A, B, C, and D.
Determine the number of rows: For four input variables, there will be (2^4 = 16) possible combinations of inputs.
List all possible combinations: Create a table with 16 rows, each representing a unique combination of the input variables.
Determine the output for each combination: Use the given logical expression to calculate the output for each combination of inputs.
Boolean Algebra Truth Tables for Logic Gate Functions
For a 2-input AND gate, the output Q is true if BOTH input A “AND” input B are both true, giving the Boolean Expression of: ( Q = A and B). Note that the Boolean Expression for a two input AND gate can be written as: A.B or just simply ABwithout the decimal point. See more
For a 2-input OR (Inclusive-OR) gate, the output Q is true if EITHER input A “OR” input B is true, giving the Boolean Expression of: ( Q = A or B). See more
For a 2-input NAND gate, the output Q is NOT true if BOTH input A and input B are true, giving the Boolean Expression of: ( Q = not(A AND B)). See more
For a single input NOT (Inverter) gate, the output Q is ONLY true when the input is “NOT” true, the output is the inverse or complement of the … See more
For a 2-input NOR gate, the output Q is true if BOTH input A and input B are NOT true, giving the Boolean Expression of: ( Q = not(A OR B)). As well as the standard logic gates there are … See more

Truth table - Wikipedia
A truth table is a mathematical table used in logic—specifically in connection with Boolean algebra, Boolean functions, and propositional calculus—which sets out the functional values of logical expressions on each of their functional arguments, that is, for each combination of values taken by their logical variables. In particular, truth tables can be used to show whether a propositional expression is true for all legitimate input values, that is, logically valid.
