Malik Zawwar Hussain, Misbah Irshad, Muhammad Sarfraz, Nousheen Zafar · 2015
In this paper, a technique, which uses cubic spline, is proposed for the interpolation of discrete time signals and illustrated with examples. The results obtained are compared with the results of nearest neighbor interpolation and linear interpolation of discrete time signals. The analysis is made by calculating errors.
