A filter is a system which modifies some special frequencies reletive to the others. As a result it is applicable in some applications when it is necessary to have different gains & phase shifts at different frequencies to perform specific filtering tasks. For example in an audio file which is corrupted by noise it is convinient to use a filter to cancel those frequencies which are affected by noise and consequently having a better sound quality. During this MATLAB experiment we are trying to cancel the noise frequencies out of the original signal frequencies to get the original signal. Due to do this task, different types of filters such as FIR and IIR filters are used. In FIR filters, we use two type of common windows such as fixed window like Hanning and adjustable window like Kaiser. In IIR filters four different types of filter such as Butterworth, Chebyshev I, Chebyshev II, Elliptic are used.

自适应滤波器的研究是现今自适应信号处理中较为活跃的课题之一。自适应滤波器与传统滤波器的最大区别是自适应滤波器能够自动地迭代调节自身的滤波器参数，以满足某种准则的要求，从而实现最优滤波。被广泛应用于航天航空、遥感、医疗等各科各领域，几乎涉及信号传输和接收过程的学科，都要应用到自适应滤波器。自适应滤波器包括两个组成部分：滤波器结构和自适应滤波算法，自适应算法为其核心部分，算法的优劣直接决定着自适应滤波器的优劣。因此，研究人员从收敛速度，稳态误差和计算复杂度方面不断改进算法。
