The wavelet transform a theoretical approach

wavelet transform is a complete tool for signal processing because with the help of wavelet transform we can obtain a high degree of time resolution and frequency resolution again we have a freedom to choose our time scale and wavelet family so wavelet transform gives us a complete and clear three dimensional plot between time,frequency and amplitude over desired time scales. The main purpose of writing this book to describe about the theory behind wavelet transform applications view of point as well as compare wavelet transform with Fourier transform as well as Sort time Fourier transform.
