PRINCIPLES OF COMMUNICATION ENGINEERING

Signals and their representations: Fourier series, Fourier transform, continuous spectra, frequency selective networks and transformers.

Basic Information Theory: Information , entropy of discrete systems, rate of transmission, redundancy, efficiency and channel capacity.

Amplitude Modulation: Frequency spectrum, power relations, basic requirements and description of various modulators, comparison. DSB, DSBSC, SSB, VSB, spectrum modulators and detectors.

Frequency Modulation: Frequency spectrum of FM, phase modulation, effect of noise, generation of FM and demodulators.

Pulse Modulation: Sampling theorem, low pass and band pass signals, elements of PAM, PWM, PPM, PCM and Delta Modulation. FDM,TDM.A.M. and FM radio transmitters and receivers. Characteristics, block diagrams.
