Introduction
Electronics is the branch of engineering which deals with the study of flow of
current in the vacuum or gas or a semiconductor .
Electronics has gained much importance due to its numerous applications in the
industry.

Introduction
The variation of a physical parameter with respect to a reference parameter is
known as a signal.
The signals are broadly classified into three types, viz
- Continuous/Analog signal
- Discrete signals
- Digital signal

i) Derive discrete time signal
ii) Quantize the discrete time signal
Introduction
System (from Latin systēma, in turn from Greek σύστημα systēma,
“whole compounded of several parts or members, system”, literary
“composition”) is a set of interacting or interdependent components
forming an integrated whole.
A system is a set of elements and relationships which are different from
relationships of the set or its elements to other elements or sets.
Electrically there are two types of systems. They are,
- Analog systems
- Digital systems
Introduction to systems
Mageshkumar G, [email protected]
An audio amplifier is an example of an analog system. The amplifier
produces an output voltage which can be any value within the range of its
power supply.
Digital systems process digital signals which can take only a limited
number of values (discrete steps), usually just two values are used: the
positive supply voltage (+Vs) and zero volts (0V).

DIGITAL SYSTEMS IS THE ONLY CONCERN OF THIS COURSE
The aim of this course is to learn the basic methods for the design of
digital circuits and provide the fundamental concepts used in the design of
digital systems.
Digital electronics is essential to understanding the design and working of
a wide range of applications, from consumer and industrial electronics to
communications; from embedded systems, and computers to security and
military equipment.
In this course you will be learning how analyze, use and design of
combinational and sequential circuits.
Digital Electronics
Course objectives
Mageshkumar G, [email protected]
Students will be able to
- Analyze different methods used for simplification of Boolean
expressions
- Design and implement combinational, and sequential circuits.
- Write simple HDL codes for the digital circuits.
