EC6402 COMMUNICATION THEORY SYLLABUS FOR 4TH SEM ECE REG 2013

ANNA UNIVERSITY CE SYLLABUS
4TH SEM ECE
REGULATION 2013
OBJECTIVES:

  • To introduce the concepts of various analog modulations and their spectral characteristics.
  • To understand the properties of random process.
  • To know the effect of noise on communication systems.
  • To study the limits set by Information Theory.
UNIT I AMPLITUDE MODULATION
Generation and detection of AM wave-spectra-DSBSC, Hilbert Transform, Pre-envelope & complex envelope - SSB and VSB –comparison -Superheterodyne Receiver.

UNIT II ANGLE MODULATION
Phase and frequency modulation-Narrow Band and Wind band FM - Spectrum - FM modulation and demodulation – FM Discriminator- PLL as FM Demodulator - Transmission bandwidth.

UNIT III RANDOM PROCESS
Random variables, Central limit Theorem, Random Process, Stationary Processes, Mean, Correlation & Covariance functions, Power Spectral Density, Ergodic Processes, Gaussian Process, Transmission of a Random Process Through a LTI filter.

UNIT IV NOISE CHARACTERIZATION
Noise sources and types – Noise figure and noise temperature – Noise in cascaded systems. Narrow band noise – PSD of in-phase and quadrature noise –Noise performance in AM systems – Noise performance in FM systems – Pre-emphasis and de-emphasis – Capture effect, threshold effect.

UNIT V INFORMATION THEORY
Entropy - Discrete Memoryless channels - Channel Capacity -Hartley - Shannon law - Source coding theorem - Huffman & Shannon - Fano codes

TOTAL: 45 PERIODS

OUTCOMES:
At the end of the course, the students would
  • Design AM communication systems.
  • Design Angle modulated communication systems
  • Apply the concepts of Random Process to the design of Communication systems
  • Analyze the noise performance of AM and FM systems
