Review of basic theory: discrete time signals and systems, Fourier theory and related theorems, sampling, multi-rate sampling and reconstruction, quantisation, time/frequency resolution, Z transform and related theorems, Laplace transform. Topics selected from: signal analysis, one-dimensional filter structure design (FIR, IIR, ARMA) with implementation on DSP hardware (processing in real-time), multi-rate structures, introduction to two-dimensional structures including array filters and beamformers, introduction to Kalman filtering, introduction to signal estimation, finite precision arithmetic effects.
