EC2311 COMMUNICATION ENGINEERING

AIM

To introduce the concepts of communication systems engineering using wire and wireless medium

OBJECTIVES

 To introduce different methods of analog communication and their significance
 To introduce Digital Communication methods for high bit rate transmission
 To introduce the concepts of source and line coding techniques for enhancing rating of
transmission of minimizing the errors in transmission.
 To introduce MAC used in communication systems for enhancing the number of users.
 To introduce various media for digital communication

UNIT I ANALOG COMMUNICATION 9

AM – Frequency spectrum – vector representation – power relations – generation of AM – DSB,
DSB/SC, SSB, VSB AM Transmitter & Receiver; FM and PM – frequency spectrum – power
relations : NBFM & WBFM, Generation of FM and DM, Amstrong method & Reactance modulations :
FM & PM frequency.

UNIT II DIGITAL COMMUNICATION 9

Pulse modulations – concepts of sampling and sampling theormes, PAM, PWM, PPM, PTM,
quantization and coding : DCM, DM, slope overload error. ADM, DPCM, OOK systems – ASK, FSK,
PSK, BSK, QPSK, QAM, MSK, GMSK, applications of Data communication.

UNIT III SOURCE CODES, LINE CODES & ERROR CONTROL (Qualitative only) 9
