Topics covered include:
• Communication engineering and signal processing;
• Convolution and correlation;
• Fourier series and transform;
• Amplitude modulation;
• Angle modulation;
• Analogue filters;
• Discrete signals and systems;
• Generating digital signals (sampling and quantisation);
• Fourier transform for discrete signals (DTFT/DFT);
• Digital filter (FIR and IIR) design;
• Random processes;
• Image processing;

Learning Outcomes

At the end of this course, students will be able to:
1. Describe the fundamentals of signal processing in time and frequency domains.
2. Describe the difference between analogue and digital signal processing.
3. Explain different types of analogue and digital filters and be able to design the filters.
4. Apply the signal processing techniques to communications engineering systems and other areas in engineering.
5. Perform modulation and demodulation for amplitude, phase and frequency modulation.
6. Describe the theory behind transmission and reception of information using a carrier waveform.
7. Demonstrate competence using the basic tools in statistics for signal processing.
