N=15, 。用Hanning窗设计一线性相位带通滤波器，观察它的实际3dB和20dB带宽。N=45，重复这一设计，观察幅频和相位特性的变化，注意长度N变化的影响。-N = 15,. Hanning window design with a linear-phase band-pass filter, observe its actual 3dB and 20dB bandwidth. N = 45, repeat the design, observe the amplitude-freque

数字滤波器 ，用matlab的GUI界面完成，可以对输入的信号进行低通，高通，带通，带阻的选择，同时能设置相应的参数。滤波的类型包括：blackman，boxcar，hanning，hamming-Digital filter matlab GUI interface, the input signal low pass, high pass, band-pass, band-stop choice, at the same time to set the appropriate paramet

用MATLAB分别利用汉明窗、汉宁窗、布莱克曼窗和凯泽窗设计一个带通滤波器-Respectively, with the use of MATLAB Hamming window, Hanning window, Blackman window and Kaiser window design a bandpass filter

Hanning加窗插值算法 采样周期为200ms，先确定谐波位置，再插值求解-Hanning windowed interpolation algorithm sampling period of 200ms, first determine the harmonic position, then interpolated to solve

fft汉宁窗 MATLAB程序 幅频特性的matlab实现 汉宁窗的产生程序，分析他们的幅度和相位响应(FFT MATLAB program Hanning window amplitude and frequency characteristics matlab program Hanning window, analysis of the amplitude and phase of their response)
