Cosine-/Sine-Modulated Filter Banks

This book covers various algorithmic developments in the perfect reconstruction cosine/sine-modulated filter banks (TDAC-MDCT/MDST or MLT, MCLT, low delay MDCT, complex exponential/cosine/sine-modulated QMF filter banks), and near-perfect reconstruction QMF banks (pseudo-QMF banks) in detail, including their general mathematical properties, matrix representations, fast algorithms and various methods to integer approximations being recently a new transform technology for lossless audio coding. Each chapter will contain a number of examples and will conclude with problems and exercises. The book reflects the research efforts/activities and achieved results of the authors in the time period over the last 20 years.

Aceasta carte acopera diverse evolutii algoritmice in reconstituirea perfecta a bancilor de filtru cosinus / sinusmodulat (TDAC-MDCT / MDST sau MLT, MCLT, MDCT cu intarziere redusa, banci complexe de filtre QMF exponentiale / cosinus / sinusmodulate) si reconstructie aproape perfecta Bancile QMF (pseudo-bancile QMF) in detaliu, inclusiv proprietatile lor matematice generale, reprezentarile matricei, algoritmi rapidi si diverse metode de aproximari intregi fiind recent o noua tehnologie de transformare pentru codificarea audio fara pierderi.
