# Undergraduate Course: Signal and Communication Systems 3 (ELEE09017)

 School School of Engineering College College of Science and Engineering Credit level (Normal year taken) SCQF Level 9 (Year 3 Undergraduate) Availability Available to all students SCQF Credits 10 ECTS Credits 5 Summary This course aims builds on Signals and Communication Systems 2 (SCEE08007) to introduce students to the fundamentals of discrete-time signal processing and communications. In the first half, the course considers discrete-time analysis techniques, gaining insights in both time-domain and frequency domain. Infinite duration signals are assumed. The second half course then considers baseband communications and information theory. Course description 1. Course overview, revision of material from the signals component of the second year course Signals and Communications 2 (SCEE08007), including an overview of continuous-time signal analysis (1 hour). 2. Revision of Nyquist's Sampling Theorem, analysis of the effect of sampling on the frequency content of a signal (anti-aliasing), and ideal and practical signal reconstruction (1 hour). 3. Discrete-time signal transformations using the Discrete-time Fourier Transform (1 hour). 4. Difference equations, digital filters, and discrete-time convolution (1 hour). 5. Derivation of the unilateral (one sided) Z-transform (1 hour). 6. The notion of linearity and the response of discrete-time systems to harmonic inputs; determining the impulse response and stability of a system from a pole-zero diagrams (2 hours). 7. Frequency response of a discrete-time linear system from its pole-zero diagram (1 hour). 8. Transform analysis of linear systems and transfer functions (using Z-transforms). (2 hours). 9. Introduction to baseband communications systems in the absence of noise (4 hours). 10. Noise, power spectral densities, and probability (3 hours). 11. Basic Error Correction, including parity check bits, and simple block codes (3 hours).
