“…In the recent years, many research of Finite Impulse Response (FIR) filters had been conducted. Some applications that could be implemented using this kind of filters are: image sampling [1], image coding [2], beamforming [3], software radio [4], audio [5], hearing aid [6] and DSP application [7] In this paper, design and realization of FIR Filter with bandwidth of 40 MHz at 50-90 MHz frequency for ISL application are done. An Equiripple method was used to design the filter because of its reliability in minimizing the magnitude errors.…”
