The Window Design Method The basic idea behind the design of linear-phase FIR filters using the window method is to choose a proper ideal frequency-selective filter [which always has a noncausal, infinite duration impulse response] and then tru

fir filter design for nois removal from speech signal..........it can be done using iir filte or different windows also

In this laboratory, we mainly focus on how to design the FIR filters using MATLAB and under certain specifications. Also, we need to:  Design FIR filters using windows (rectangular and Hamming) to meet certain specifications  Ev

1 设计一个ＦＩＲ数字低通滤波器， 满足一组模拟滤波器的指标参数；分别采用三角窗、hamming窗、blackman窗和kaiser窗进行设计。比较不同窗的设计效果。要求描绘滤波器的脉冲响应、窗函数以及滤波器的幅频和相频响应曲线。 2. 用上述设计滤波器完成几组给定信号的滤波。 3.设计数字高通、带通、带阻滤波器，要求描绘滤波器的脉冲响应以及滤波器的幅频和相频响应曲线-1、A design of a FIR digital low-pass filter, analog filters to m
