FIR (Finite Impulse Response) Filter: Finite-length unit Impulse response filter, also known as non-recursive filter, is the most basic component of digital signal processing system, it can guarantee arbitrary amplitude characteristics at the same time with strict Of the linear phase-frequency characteristics, while the unit sampling response is finite, so the filter is a stable system. Therefore, FIR filter in communication, image processing, pattern recognition and other fields have a wide range of applications.
