Fourier analysis and spectra: Fourier series and transforms, single and double-sided spectra, transfer functions and filters. Analogue modulation: the reasons for frequency translation, amplitude modulation, frequency modulation, phase modulation, modulators and detectors, coherence. Digital modulation: keying methods - frequency shift keying, phase shift keying (differential and absolute), quadrature amplitude shift keying, higher-order schemes. Noise and interference: noise types, noise figure and temperature, signal-to-noise ratio calculations, non-linearities, mixing and intermodulation, harmonics, signal distortion. Multiplexing: the need for multiplexing, multiplexing methods and hierarchies - frequency division multiplex, time division multiplex, code division multiplex. Transmission media: transmission lines - twisted pair, open wire, coaxial lines and waveguides. Radio propagation - HF, VHF and UHF, microwave and satellite. Fibre optics - stepped index, graded index and mono mode.
