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.

This paper is an overview of the sources and nature of various transient over voltages and the problems that may result in a low voltage ac distribution system. Voltage transients may be repeatable transients or random impulses and they have got remarkable effects on semiconductors, electrochemical contacts, insulation etc. Switching parallel loads on the same branch of distribution system as well as lighting are responsible for these transient overvoltages. Low voltage ac mains system should be protected from these transient overvoltages. For ....etc

Abstract
This paper proposes a two-phase scheme for removing salt-and-pepper impulse noise. In the first
phase, an adaptive median filter is used to identify pixels which are likely to be contaminated by noise
(noise candidates). In the second phase, the image is restored using a specialized regularization method
that applies only to those selected noise candidates. In terms of edge preservation and noise suppression,
our restored images show a significant improvement compared to those restored by using just nonlinear
filters or r ....etc

This seminarsr provides the experience of applying an advanced version of our former spurious power suppression technique (SPST) on multipliers for high-speed and low-power purposes. To filter out the useless switching power, there are two approaches, i.e., using registers and using AND gates, to assert the data signals of multipliers after the data transition. The SPST has been applied on both the modified Booth decoder and the compression tree of multipliers to enlarge the power reduction. The simulation results show that the SPST implementat ....etc

Adaptive Blind Noise Suppression in some Speech Processing Applications

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.

Abstract:

This project provides the experience of applying an advanced version of Spurious Power Suppression Technique (SPST) on multipliers for high speed and low power purposes. When a portion of data does not affect the final computing results, the data controlling circuits of SPST latch this portion to avoid useless data transition occurring inside the arithmetic units, so that the useless spurious signals of arithmetic units are filter out. Modified Booth Algorithm is used in this project for mul ....etc
