Abstract

Digital filters are used in communication systems. The Digital filter performance is important as a good result. Design of FIR (finite impulse response) filter satisfy demand condition is required. Maximum side lobe is minimized by Hamming window. The new window has a main lobe width approximately same as Hamming window. The new window has a wider main lobe width in proposed window. Digital Signal processing two main applications of windows is: Finite impulse response (FIR) and Fast Fourier transforms (FFT) from infinite impulse response (IIR) filters. Windows and FFT (Fast Fourier transform) analysis, both are decrease side lobes. So this effect is called ‘Leakage Effect.
