Objective:

This chapter introduces the most fundamental logic gates and also the most fundamental of all registers along with basic applications. Moreover, to make the presentations more effective and connected to the physical implementations, the corresponding electronic circuits, using CMOS architecture, are also included. Even though many other details will be seen later, the ...
