Abstract
The main focus of the current work is to introduce the new numerical technique based upon theHaar scale 3 wavelets for the solution of 1D- hyperbolic telegraph equation. In this scheme,spatial discretization is done by scale 3 Haar wavelets. The collocation method is used with Haar scale 3 wavelets to convert 1D- hyperbolic telegraph equation into the system of algebraic equations which are further solved with the help of Thomas algorithm. The proposed scheme is tested on four different equations of above said types to establish the competency of the proposed scheme.
