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

simple counters Counting is a fundamental function of digital circuits. A digital counter consists of a collection of flip-flops that change states (set or reset) in a prescribed sequence

Analysis Analyze existing circuits to determine their function Synchronous sequential circuit The basic modeling structure Two circuit models: Mealy model& Moore model Three approach used to describe the circuit: Logic function equation
