1)Response Type(响应类型):有低通、高通、带通、带阻等设计。 2)Design Method(设计方法):有IIR和FIR两大类。 3)Filter Order(滤波器阶次):阶次可以根据自己的需要设定,也可以直接选择最小阶次。 4)Frequency Specifications(频率参数):根据自己所需要的参数进行设定。 例:设计一个一下参数的滤波器: 1)巴特...
对于FIR滤波器，a为1% 输入信号fs = 1000; % 采样频率t = 0:1/fs:1-1/fs; % 时间向量f = 5; % 信号频率x = sin(2*pi*f*t); % 生成正弦波信号% 滤波处理y = filter(b, a, x);% 绘制原始信号和滤波后的信号figure;subplot(2, 1, 1);plot(t, x);title('原始信号...
PlotFilter This program plots filter responses. The program takes as input a filter specification in [b,a] (numerator, denominator polynomials) form. It offers a number of different types of frequency response plots. • log: Log amplitude plot with a limited dynamic range. • log-radian: ...
(7)Step Response——阶跃响应分析 (8)Pole/Zero Plot——零极点图分析 三:FDAtool程序导出式滤波器设计 1.依据二中滤波器参数生成滤波器(参数输入后点击design filter) 2.生成后,点击file—Generate MATLAB code—Filter Design Function。生成对应程序并保存 ...
Design a 40th-order lowpass Chebyshev type II digital filter with a stopband edge frequency of 0.4 and stopband attenuation of 50 dB. Plot the frequency response of the filter using its coefficients in the CTF format. Get [B,A] = cheby2(40,50,0.4,"ctf"); freqz(B,A,"ctf") Design...
visualize(weightFilt)plots the magnitude response of the frequency-weighted filterweightFilt. The plot is updated automatically when properties of the object change. example visualize(weightFilt,N)uses anN-point FFT to calculate the magnitude response. ...
plotResponse(H,x,coeff)plots the range-Doppler response after performing a matched filter operation onxusing the matched filter coefficients incoeff. This syntax is available when you set theRangeMethodproperty to'Matched filter'. plotResponse(___,Name,Value)plots the angle-Doppler response with add...
For example, a ninth-order Butterworth lowpass filter with a cutoff frequency of 400 Hz, based on a 2000 Hz sampling frequency, is [b,a] = butter(9,400/1000); To calculate the 256-point complex frequency response for this filter, and plot the magnitude and phase withfreqz, use ...
