OBJECTIVES:

 To introduce basic postulates of Boolean algebra and shows the correlation between Boolean
expressions
 To introduce the methods for simplifying Boolean expressions
 To outline the formal procedures for the analysis and design of combinational circuits
 and sequential circuits
 To introduce the concept of memories and programmable logic devices.
 To illustrate the concept of synchronous and asynchronous sequential circuits
