Phys.426 Communicative and Digital Electronics 3+1*

LEARNING OBJECTIVES:

The primary aim of this course is to:
 describe the concepts of electronics in communication.
 Communication techniques based on analog modulation, analog and digital pulse
modulation including PAM, PWM, PPM, ASK, PSK, FSK are described in detail.
 Communication and Navigation systems such as GPS, satellite and mobile telephony
systems are introduced.

LEARNING OUTCOMES:

At the end of this course, students will be able to:
 This paper aims to describe the concepts of electronics in communication. In this
course,students will receive an introduction to the principle, performance and
applications ofcommunication systems.
 Students will learn the various means and modes of communication. They will gain
anunderstanding of fundamentals of electronic communication system and
electromagneticcommunication spectrum with an idea of frequency allocation for radio
communicationsystem in India.
 They will gain an insight on the use of different modulation and demodulation
techniquesused in analog communication
 Students will be able to analyse different parameters of analog
communicationtechniques.They will learn the need of sampling and different sampling
techniques where they cansample analog signal.
 Students will learn the generation and detection of a signal through pulse and
digitalmodulation techniques and multiplexing.They will gain an in-depth
understanding of different concepts used in a satellitecommunication system.
 This paper will essentially connect the text book knowledge with the most
popularcommunication technology in real world.
