4 points * 26 lectures, 13 tutorials, 12 laboratory hours * Second semester * Clayton * Prerequisites: ECS2340 (Telecommunications) at PI level, and MAT3910 * Corequisites: ECS3312 (Circuit theory III) and MAT3920 (Statistical methods)
Analog modulation: amplitude modulation - envelope-phase representation, envelope detection, spectra; double-sideband suppressed-carrier - spectrum, product detection, the Costas loop; single-sideband modulation - methods of generation and detection; phase modulation and frequency modulation - generation and detection, spectra, band width considerations. Signal transmission and filtering: signal distortion in transmission - linear and non-linear distortion, equalisation; filters - standard lowpass and bandpass characteristics, pulse shaping filters, distortion. Introduction to random signals and noise: description of random processes, averages, stationarity and ergodicity, power and power spectrum; shot noise and thermal noise; detection in the presence of noise. Digital transmission: sampling, quantisation and time-division multiplexing; baseband digital data transmission. Communication systems: AM and FM radio and TV signal formats; microwave radio systems; optical fibre transmission; communication system design principles.
