Magnetic Properties of Titanium Substituted Ni – Zn Ferrites
The polycrystalline samples of mixed ferrites Ni0.5 x Zn0.5TixFe2 2xO4 with x = 0.0, 0.1, 0.2, 0.3, 0.4 and 0.5 were prepared by ceramic method. Single phase formation is confirmed by x ray diffraction. It is seen that, for all samples the lattice constant remains constant this id due to constant in ionic radii. In […]
Effect of Temperature on the Electric Power of Si InAs and GaAs Based Solar Cells
The electrical power is a nominal quantity which indicates the performance of the solar panels. It depends on the sunshine and also on the properties of the material used. In this work we are interested in the properties of materials to study the evolution of electrical power as a function of the temperature of the […]

Study on Speech Compression and Decompression by using Discrete Wavelet Transform IJTSRD
Speech signal can be compressed and decompressed by discrete wavelet transform technique. Discrete wavelet transform compression is based on compressing speech signal by removing redundancies present in it. Speech compression is a technique to transform speech signal into compact form. Objective of compressing speech signal is to enhance transmission and storage capacity. The compression parameters […]
