Abstract

In this work, a kind of wavelet used in many mathematical problems and numerically solved, such as heterogeneity and integral equations, are presented. The solution is close to the exact solution using the matrix of integral operations. In this paper, the issues of limited value were solved and good solutions were found. Solved examples show that.
In addition, the proposed theory was used to process signals for one dimension and the noise and signal pressure were removed this was applied to some kind of signal.
