Overall aims and purpose
To provide an introduction to the principles and analysis of analogue and digital communications systems.
• Time and frequency representation of both discrete and continuous signals. Fourier series and Fourier transforms. • Convolution and Sampling theorem. • Time-limited and Band-limited signals. Single and double-sided spectra. • Amplitude modulation – AM, DSB-SC, SSB, VSB, Signal Spectrum and Power Efficiency. • Frequency and Phase modulation – Signal Spectrum, Carson’s rule. • Pulse Amplitude Modulation – Instantaneous, Natural and Flat-Top Sampling. • Instantaneous Sampling, Nyquist criteria and Aliasing. • Quantisation and Pulse Code Modulation – bit rate, quantisation noise and companding. • Digital modulation (Baseband and passband). • Matched Filters and Inter-Symbol Interference
