Comparative Analysis of a High Pass Finite Impulse Response (FIR) Filter Designed and Simulated by Window Methods

The design of digital filters is a deceptively complex topic. although filters are easily understood and calculated, the practical challenges of their design and implementation are significant and are the subject of much advanced research. in this research paper, a high pass fir filter is designed and simulated using gaussian, taylor and hanning windows. the three windows are compared on the basis of their magnitude responses, step responses, impulse responses and phase responses and the results are presented. the comparative result shows that the proposed design of taylor window is the most efficient of the three windows.
