    To what extent does a mature and cyclical product market drive corporate restructuring? Use an example to discuss whether restructuring transforms market and financial performance. A business‚ which has a product that runs in a cyclical and mature market‚ will eventually not have the ability to ‘grow’ anymore as it will reached the ‘top’. Therefore to continue making its business profitable‚ increase shareholder value and work more effectively they under go corporate restructuring. This is a

    Digital signal processing Digital signal processing Digital signal processing (DSP) is the mathematical manipulation of an information signal to modify or improve it in some way. It is characterized by the representation of discrete time‚ discrete frequency‚ or other discrete domain signals by a sequence of numbers or symbols and the processing of these signals. The goal of DSP is usually to measure‚ filter and/or compress continuous real-world analog signals. The first step is usually to convert

    Power Filter Using Wavelet Transforms Abstract— The effect of Power Quality (PQ) Disturbances on power utilities are increasing day by day with wide spread use of non – linear loads. “Harmonics is one such disturbance which will cause the power system”. These disturbances are detected and compensated in a better means by using Active Power Filters (APF). The identification and reference current generation is carried out by using Wavelet Transform (WT) Theory. Wavelet Transform Theory at present is one

    College of Engineering‚ Kakinada. ABSTRACT Speech compression is the technology of converting human speech into an efficiently encoded representation that can later be decoded to produce a close approximation of the original signal. The wavelet transform of a signal decomposes the original signal into wavelets coefficients at different scales and positions. These coefficients represent the signal in the wavelet domain and all data operations can be performed using just the corresponding wavelet coefficients

    technology of digital watermarking is received a large deal of attention. Generally‚ digital watermarking techniques are based on either spread spectrum methods or changing the least significant bits of selected coefficients of a certain signal transform. For speech watermarking‚ to ensure the embedded watermark is imperceptible‚ the audio marking phenomenon is considered together with these conventional techniques. In addition‚ a speech watermarking system should be robust to various speech

    data transmission is possible. ADSL uses carrierless-amplitude phase (CAP)to modulate signals over the line. It separates the line into three channels; upstream access‚ downstream access‚ and voice. Another method of modulation is performed with discrete multitone (DMT) in which the line is divided into 256 subchannels each having 4.3125 kHz of bandwidth utilizing quadrature amplitude modulation (QAM)
