In contrast to what you might expect, the procedure to create a simple high-pass filter is not a variation on the procedure to create a low-pass filter that I explained in How to Create a Simple Low-Pass Filter. This article is complemented by a Filter Design tool that allows you to create your own custom versions of the example filter that is shown below, and download the resulting filter coefficients. 313–317).Summary: This article shows how to create a simple high-pass filter, starting from a cutoff frequency \(f_c\) and a transition bandwidth \(b\).

Design of programmable, efficient finite impulse response filter based on distributive arithmetic algorithm. In IEEE proceedings of international conference on communications, circuits and systems, Milpitas, July 2009 (pp. An ALU-based universal architecture for FIR filters. The results suggest that constraining the bit width and pessimism reduction has less than 1% impact on the filter accuracy within limits specified by architecture specifications.
We also performed an RTL simulation for the filter and compared the functional verification results with a golden double-precision implementation in MATLAB. The obtained results are superior to those of previous implementations for exact filter specifications.
MATLAB HDL coder generated Register Transfer Level (RTL) code was implemented on Xilinx Kintex 7 using Vivado software. The implementation was created using a novel high-level synthesis design method, which reduces pessimism associated with bit-width constraints in synthesis for inputs, outputs, and intermediate data nodes. The filter was designed using MATLAB and Simulink and code generated using HDL Coder from MathWorks. This paper proposes an area, speed and power-optimized band-pass digital signal processing filter targeted for Kintex-7 Field Programmable Gate Array device.
