FGPA Based Hardware Level Analysis of Inverse Sinc Filters
In this paper, the authors focus on effect of cut-off frequency on the transition curve of the Inverse Sinc filter. The Matlab frequency visualization tool, fvtool, was used to analyze the transition bandwidth variation in response to the change in cut off frequency of the digital filter. One of the imperative facilities provided in Matlab software, to generate the Hardware Description Language (HDL) for the filter object i.e. 'GenerateHDL' command, was used and the digital filter was hardwired in a reconfigurable device: Field Programmable Gate Array (FPGA).
