EC6402 COMMUNICATION THEORY – SYLLABUS – R- 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
