PURPOSE
- The aim of the module is to develop the students
understanding of, noise and how it affects analogue
and digital communications, electromagnetic wave
propagation and antennas, transmission line techniques
and optical fibre communications. |

INDICATIVE
CONTENT- Noise: Noise sources, noise in the frequency
and time domains. Signal-to-noise ratio, noise figure,
noise temperature. Errors in digital systems, BER
calculations.
Transmission lines: Primary line constants, secondary
coefficients, velocity of propagation, characteristic
impedance. Smith charts, impedance matching, stubs.
Guided waves Antennas: Electromagnetic wave propagation.
Antennas-basic properties, radiation resistance,
polarisation, gain, beamwidth. Antenna types and
reflector aerials and their properties.
Optical fibres: Propagation in optical fibres. Fibre
types, dispersion mechanisms. Optical sources and
detectors. |
