WebMar 23, 2024 · One way to avoid this is by designing a Minimum-phase filter. That is an FIR filter whose impulse response is not symmetric – instead, it is designed to minimize group delay by placing higher valued coefficients first along the delay line. This, however, comes at the cost of a non-linear phase response. WebFigure 1. Conventional FIR Application The output of each register is called a tap and is represented by x (n), where n is the tap number. Each tap is multiplied by a coefficient h (n) and then all the products are summed. The equation for this filter is: For a linear phase response FIR filter, the coefficients are symmetric around the center ...

WebOct 11, 2016 · Although this seems to be an easily implementable task, the synthesizing tools require an adaptation of the straightforward digital filter implementation for an optimal mapping. Using the example of a symmetric FIR filter with 90 taps, we demonstrate the performance of the proposed structure with FPGAs from Xilinx and Altera.
