**Topics**- Multirate Signal Processing: filter banks, multirate systems, filtering, decimation, upsampling, polyphase, perfect reconstruction, aliasing cancellation, signal representation and signal decomposition using vectors and matrices.
- Wavelets: wavelets from filter banks, bases, frames, orthogonality and biorthogonality, multiresolution, smoothness, vanishing moments, time-frequency and time-scale analysis, continuous-time and discrete-time wavelet transform, famous wavelet pairs, wavelet packet, symmetric extensions, complexity issues.
- Design methods: spectral factorization, polyphase matrix factorization, lattice structure, ladder structure (lifting scheme), integer wavelets, cosine modulation, time-domain optimization.
- Applications: Audio/Image/Video compression -- lossy and lossless, subband coding, quantization effect, signal denoising, wavelet shrinkage, inverse halftoning, database retrieval and indexing, multicarrier modulation, transmultiplexers, edge detection.
