    No full text
    A brief theory of wavelet transforms and their effective computation method with an emphasis on the considerations of the choice of pressure angle are presented in this paper. This is followed by the numerical results with related graphs. The procedure used in this paper include the numerical simulation of the dynamics of a gear transmission system. This approach is to first develop a clear understanding of the fundamentals of a particular research topic and to take into account the vast amount of practical data for industry. The aim is to produce guidelines for gear design which will improve gear performance in terms of accuracy, efficiency, vibration and noise. By developing improved metrology methods the aim is to help the identification of error sources in manufacture and to predict performance in operation
