Rate Conversion

Application of multirate techniques to improve digital filter design and implementation are considered in this chapter. FIR and IIR filter design and implementation for sampling rate conversion by integer and rational factors are presented. Sharp narrow-band and wide-band multirate design techniques are discussed. Accurate designs of FIR and IIR half-band filters are described in detail. Several examples are provided to illustrate the multirate approach to filter design.

Recent Developments

The vibration absorber has been used for vibration control purposes in many sectors of engineering from aerospace, to automotive to civil, for the past 100 years or so. A limitation of the device, however, is that it acts like a notch filter, only being effective over a narrow band of frequencies. Recent developments have overcome this limitation by making it possible to tune the device over a range of frequencies. This has been achieved by incorporating a variable stiffness element that can be adjusted in real-time. In this paper, some ways in which stiffness change can be achieved in practice are reviewed and some examples of prototype adaptive tuned vibration absorbers (ATVAs) are described. A simple control scheme to automatically tune an ATVA is also presented.

Recent Developments

Ultra broad band (UWB) has emerged as a leading technology for potential wireless applications due to recent developments in wideband impulse technology, low power and communication. When opposed to traditional narrow band networks, ultra-wide band (UWB) wireless communications takes a completely different approach to wireless communication. The technology is generating a lot of buzz around the world. This paper outlines the characteristics, its applications, and advantages and disadvantages. It main focuses on the future change of UWB.
