This course aims to extend the continuous-time analysis of signals and systems to discrete time. This course provides the following: Review of Discrete-time signals and systems, Correlation, Frequency Domain Concepts, Analogue to Digital conversion, Sampling, Quantization, LTI systems described by difference equations, FIR and IIR Filters design, and implementation. Z-transform applications, Discrete-Time Fourier Transform, Fast Fourier Transforms (FFT).
