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

Registers, formed from collection of flip -flops, are used to store or manipulate data or both. Input and output function associated with registers include Parallel input/ Parallel output Serial input/ Serial output Parallel input/ Serial output OSerial input parallel output

FLIP-FLOPS Add the certain combinational logic circuit to the input of the original flip- flop New

Let be the set of all input variables, X={, X1, .Xn} Let y be the set of all output variables, y={Y, 1 ...m} o The combinational function, F, operated on the input variable set, to produce the output variable set y. o The output is related to the input as

INTRODUCTION Level five Complex Systems, Function Units from levels Two through Four Level four More complex Function Logic Units, e.g. microprocessor Third IC level (VLSI) Level three Function Logic Units, e.g. adders, Second IC level counters, multiplexers (MSI and LSI) Level two Function Logic Units, e.g. gates, NOT, AND, NAND, EX-OR First IC level (SSI)

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

Digital system: entity can process, transfer and store any kind of digital signals is Composed of individual digital logic circuits which are designed to perform specified function

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