Design of FIR filter using hanning window, hamming window and modified hamming window
Digital filters are widely used in many digital signal processing applications. Therefore, digital filtering is one of the basic needs of digital signal processing. This paper introduces the definition and basic principles of FIR digital filters, and the design based on MATLAB.After the description of the process of design, the matlab program is used to implement FIR filter using modified coeff...
متن کاملDesign and Performance Analysis of Low Pass Fir Filter Using Hamming and Kaiser Windows
Digital Signal Processing is used in many areas where analogue method was difficult. Filters are used to separate or combine different frequencies. In this paper low pass filter has been designed and simulated using different windows techniques. Hamming and Kaiser Windows techniques are used along with Rectangular window technique for the design analysis by using matlabs. The performances of al...
متن کاملDesign of FIR Filter Using Hamming Window
Digital filters are pervasive in the present era of communication systems. As a result good digital filter performance is important and hence to design a digital finite impulse response (FIR) filter satisfying all the required condition is a demanding one. This report deals with the design of FIR digital filter using hamming window technique. This window is optimized to minimize the maximum (ne...
متن کاملNovel Particle Swarm Optimization for Low Pass FIR Filter Design
This paper presents an optimal design of linear phase digital low pass finite impulse response (FIR) filter using Novel Particle Swarm Optimization (NPSO). NPSO is an improved particle swarm optimization (PSO) that proposes a new definition for the velocity vector and swarm updating and hence the solution quality is improved. The inertia weight has been modified in the PSO to enhance its search...
متن کاملLecture 17: FIR Design by Windowing, Kaiser Window & Optimal Approximation
The FIR techniques are based purely in discrete-time, unlike the previous techniques for IIR design that were designed from the transformation of filters specified in continuous time. Recall ideal LPF H(e jω) = 1 |ω| < ω c 0 else and h d [n] = sin ω c n πn ∀n What happens if we just truncate h d [n] to a finite of samples? h[n] = h d [n] −M ≤ n ≤ M 0 else It is equivalent to convolution in freq...
