SOME UNCONVENTIONAL SIGNAL PROCESSING APPLICATIONS OF MULTIRATE TECHNIQUES



INTRODUCTION
Multirate digital signal processing systems are characterized
by unequal sampling rates at various stages in the system. In
recent years, there has been a growing interest in the design
and applications of such systems. In most cases, the multirate
concepts have been used in some conventional applications
such as subband coding of signals, transfer of data to
and f ....etc

Area of a Triangle
Until now, our work with triangles has been limited to right triangles. However,
the concepts developed in Chapter 5 can be extended to all triangles. Every triangle
has three sides and three angles. If any three of the six measures of a
triangle are known (provided at least one measure is the length of a side), then
the other three measures can be found. This is called solving the triangle

In many applications of speech processing the noise reveals some specific features. Although the noise could be quite broadband, there are a limited number of dominant frequencies, which carry the most of its energy. This fact implies the usage of narrow-band notch filters that must be adaptive in order to track the changes in noise characteristics. In present contribution, a method and a system for noise suppression are developed. The method uses adaptive notch filters based on second-order Gray-Markel lattice structure. The main advantages of ....etc

Ultra Sonic Motor

Introduction
ULTRA SONIC motor is a newly developed motor, and it has excellent performance and many useful features, e.g.: high-torque density, low speed, compactness in size, no electromagnetic interferences, and so on. USM is a kind of piezo motor. The proposed speed control scheme is assumed for these applications because they require quick and precise speed control of actuators for various load conditions. A speed control method of USM using adaptive control is proposed.

Atop each of the Trump towers in New York City, there's a new type of wireless transmitter and receiver that can send and receive data at rates of more than one gigabit per second -- fast enough to stream 90 minutes of video from one tower to the next, more than one mile apart, in less than six seconds. By comparison, the same video sent over a DSL or cable Internet connection would take almost an hour to download.

This system is dubbed 'WiFiber' by its creator, GigaBeam, a Virginia-based telecommunications startup. Although the technolo ....etc
