Simulation Design of Finite Impulse Response Filter by MATLAB

In digital control system, interference, which is mixed in the input signal, has a great effect to performance of the system. Therefore, process of input signal has to be done to get useful signal. Finite impulse response filter plays an important role in the process of digital signal. This paper introduces the design that finite impulse response filter is simulated by MATLAB to simplify the complicated computation in simulation and to improve the performance of filter.
