Synthesis of Linear Phase Sharp Transition FIR Digital Filter

This paper proposes a new technique for synthesis of a sharp transition, equiripple passband, low arithmetic complexity, linear phase lowpass FIR filter. The frequency response of the filter with narrow transition width is modeled using trigonometric functions of frequency and its transfer function is evolved in frequency and time domain. The synthesized filter proves to be a good alternative t...

FPGA Design of Parallel Linear-Phase FIR Digital Filter Using Distributed Arithmetic Algorithm

Based on fast FIR algorithms (FFAs), we propose distributed arithmetic algorithm based new parallel FIR filter architectures, which are beneficial to symmetric convolutions in terms of the hardware cost. Multipliers are the major portions in hardware consumption for the parallel FIR filter implementation. The proposed new structures exploit the nature of symmetric coefficients of odd length and...

Analysis of Four Parallel and Five Parallel Linear Phase FIR Digital Filter Using FFA Algorithm

This study presents an architectural approach to the design of Low Area and high speed linear phase Finite Impulse Response (FIR) digital filter. FIR digital filters are used in DSP by the virtue of its, linear phase, fewer finite precision error, stability and efficient implementation. In the proposed architecture, we are introduced five parallel linear phase fir filter to obtain the high spee...

Novel Linear Phase Condition for Digital Filter

This paper describes a linear phase digital filter with novel linear phase condition. A conventional linear phase digital filter is an FIR filter with coefficients of oddor even –symmetry and whose group delay NTs/2 where N is the number of the FIR filter taps and Ts is the sampling period; its group delay time resolution is Ts/2. We have generalized the linear phase condition, and with our nov...
