Implementation of Digital FIR Low-Pass Filter with MATLAB

Using MATLAB development software, I have successfully programmed and implemented a digital FIR low-pass filter functionality. The program features straightforward execution with immediate filtering results. Implementation highlights include additional configurable parameters such as filter order selection and cutoff frequency adjustment options, allowing users to customize the filter according to specific requirements. The algorithm employs windowing methods for filter coefficient generation, with optimized computational efficiency through vectorized operations. Program performance has been enhanced for greater stability and efficiency, incorporating error handling for parameter validation. Beyond core filtering capabilities, this implementation offers extended customization options and improvements to better serve diverse user needs. The filter design utilizes frequency sampling techniques with Hamming window implementation to achieve optimal frequency response characteristics.
