Summary  This course aims builds on Signals and Communication Systems 2 (SCEE08007) to introduce students to the fundamentals of discretetime signal processing and communications. In the first half, the course considers discretetime analysis techniques, gaining insights in both timedomain 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 continuoustime signal analysis (1 hour).
2. Revision of Nyquist's Sampling Theorem, analysis of the effect of sampling on the frequency content of a signal (antialiasing), and ideal and practical signal reconstruction (1 hour).
3. Discretetime signal transformations using the Discretetime Fourier Transform (1 hour).
4. Difference equations, digital filters, and discretetime convolution (1 hour).
5. Derivation of the unilateral (one sided) Ztransform (1 hour).
6. The notion of linearity and the response of discretetime systems to harmonic inputs; determining the impulse response and stability of a system from a polezero diagrams (2 hours).
7. Frequency response of a discretetime linear system from its polezero diagram (1 hour).
8. Transform analysis of linear systems and transfer functions (using Ztransforms). (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).
