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

Sequential Circuit Models Yo Combinational logic Universal combinational circuit model No memory units No feedback from logic outputs back to the inputs

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
