EC6651 COMMUNICATION ENGINEERING syllabus-subject-notes-pevious-year-questions-papers-bank

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
Primary communication – entropy, properties, BSC, BEC, source coding : Shaum, Fao, Huffman
coding : noiseless coding theorum, BW – SNR trade off codes: NRZ, RZ, AMI, HDBP, ABQ,
MBnBcodes : Efficiency of transmissions, error control codes and applications: convolutions & block
codes.

UNIT IV MULTIPLE ACCESS TECHNIQUES 9
SS&MA techniques : FDMA, TDMA, CDMA, SDMA application in wire and wireless communication : Advantages (merits) :

UNIT V SATELLITE, OPTICAL FIBER – POWERLINE, SCADA 9
Orbits : types of satellites : frequency used link establishment, MA techniques used in satellite
communication, earth station; aperture actuators used in satellite – Intelsat and Insat: fibers – types:
sources, detectors used, digital filters, optical link: power line carrier communications: SCADA

OUTCOMES:
 Ability to understand and analyse, linear and digital electronic circuits.
