Karnaugh maps It is a matrix of squares. each square represent a minterm or maxterm from a Boolean equaTion N-variable karnaugh map have 2 squares The binary numeral on the sides of k-map is the variable coordinates

A function is a term used in mathematics and logic to denote a relationship between input and output variables. Each variable is restricted to binary (0, 1) values The relationship is the complex of three primitive functions (And \\Not\\Or)

Binary Arithmetic Binary arithmetic Addition - Augend+addend+carry-in Sum ....carry-out Subtraction - Minuend-subtrahend-borrow-in difference ...borrow-out

Binary Code Natural Binary Coded Decimal (BCD) Decimal BCD group of four binary digits represent 0000 a single decimal digit

Positional Number System Number system use positional notation to represent value. The position of the character(numeral) in a character string (collection of possible numerals) indicate value as well as the character itself. Radix (base) is the number of numeral characters in the character set of positional number system. Position Weiaht is a constant that represents the value of a position. Different position has different weight. It is the integer power of radix
