Course Objectives

This course provides in-depth knowledge of switching theory and the

design techniques of digital circuits, which is the basis for design of any digital circuit. The main objectives are:

• To learn basic techniques for the design of digital circuits and fundamental concepts used in the design of digital systems.
• To understand common forms of number representation in digital electronic circuits and to be able to convert between different representations.
• To implement simple logical operations using combinational logic circuits
• To design combinational logic circuits, sequential logic circuits.
• To explain the complete response of R-C and R-L-C transient circuits.
• To explain clippers, clampers, switching characteristics of transistors and sampling gates.
• To construct various multivibrators using transistors, and design of sweep circuits.

Course Outcomes

Upon completion of the course, students should possess the following

skills:

• Be able to manipulate numeric information in different forms, e.g. different bases, signed integers, various codes such as BCD.
• Be able to manipulate simple Boolean expressions using the theorems and postulates of Boolean algebra and to minimize combinational functions.
• Be able to design and analyze small combinational circuits and to use standard combinational functions/building blocks to build larger more complex circuits.
• Be able to design and analyze small sequential circuits and devices and to use standard sequential functions/building blocks to build larger more complex circuits.
• Understand the applications of diode as integrator, differentiator, clippers, and clamper circuits.
• Learn various switching devices such as diode, transistor, SCR. Difference between logic gates and sampling gates
• Design Mutivibrators for various applications, synchronization techniques and sweep circuits.
