The main thrust is to provide students with a solid understanding of a number of important and related advanced topics in digital signal processing such as Wiener filters, power spectrum estimation, signal modeling and adaptive filtering. Scores of worked examples illustrate fine points, compare techniques and algorithms and facilitate comprehension of fundamental concepts. Also features an abundance of interesting and challenging problems at the end of every chapter.
Filter banks are arrangements low pass, bandpass, and highpass filters used of for the spectral decomposition and composition of signals. They play an important role in many modern signal processing applications such as audio and image coding. The reason for their popularity is the fact that they easily allow the extractionof spectral components of a signal while providing very efficient implementations. Since most filter banks involve various sampling rates, they are also referred to as multirate systems....

Filter Banks and Wavelets
The methods of designing bases that we will employ draw on ideas ﬁrst used in the construction of multirate ﬁlter banks. The idea of such systems is to take an input system and split it into subsequences using banks of ﬁlters. This simplest case involves splitting into just two parts using a structure such as that shown in Fig. 35.1. This technique has a long history of use in the area of subband coding: ﬁrst of speech [1, 2] and more recently of images [3, 4]. In fact, the most successful image coding schemes are based on...

nterpolation is the estimation of the unknown, or the lost, samples of a signal using a weighted average of a number of known samples at the neighbourhood points. Interpolators are used in various forms in most signal processing and decision making systems.
