摘要
在数字控制系统中输入信号里所含的干扰对系统的性能会产生很大的影响,因此需对输入的信号进行处理,以提取有用信号.有限冲激响应滤波器在数字信号处理中发挥着重要作用.本文着重介绍采用MATLAB软件对有限冲激响应滤波器进行仿真设计,从而简化了设计中繁杂的计算,并提高了滤波器的滤波性能.
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.
