Digital Signal Processing (DSP) plays vital roles in various engineering applications. Vedic mathematics is the ancient mathematics which has a unique technique of mental calculation with the help of simple rules and principles based on 16 sutras. The use of multiplier with higher speed is of utmost importance to any DSP. Multiplication play important role in filter designing, convolution, correlation etc. Convolution is the basic concept of designing Finite Impulse Response (FIR) filter. FIR filter is also called convolution filter. Our effort has proved the efficiency of Urdhava-Tiryagbhyam method for multiplication which delivers a difference in the actual process of multiplication itself. In this paper, we design FIR filter using Urdhava-Tiryagbhyam sutra. This algorithm is implemented in MATLAB and performed in GUI. FIR filter based on UrdhavaTiryagbhyam reduces the processing time as compared to inbuilt function of MATLAB. The results show that UrdhavaTiryagbhyam has greater impact on improving the speed of FIR filter.
