CSE 443: Digital Signal Processing

Offered Under: B.Sc. in Computer Science & Engineering (CSE)

This senior-level course serves as an introduction to the fundamentals, implementation and applications of DSP. Will be useful for students looking to do graduate courses in communications and signal processing. Topics include: The mathematics of signals and linear systems; Fourier and Laplace transforms, discrete Fourier and Z transforms; Analogue filters: approximation theory, Butterworth, Bessel, Chebyshev and elliptic filters; Filter impulse and frequency responses, stability, and sensitivity; Sampling continuous signals: the sampling theorem, reconstruction, and aliasing; The discrete Fourier transform (DFT) and the fast Fourier transform (FFT); Fundamentals of the design and realization of finite impulse response (FIR) and infinite impulse response (IIR) digital filters; Digital processing of analog signals, including applications of digital signal processing (DSP) and programmable DSP chips; The representation and modelling of non-deterministic (random) signals, correlation functions, and power density spectra.
