Description: FIR数字滤波器的设计方法主要是建立在对理想滤波器频率特性作某种近似的基础上的。这些近似方法有窗函数法、频率抽样法、最佳一致逼近法。在这里只讨论窗函数法。程序中也是采用了这种方法。-FIR digital filter design method is mainly based on the frequency characteristics of the ideal filter for some kind of approximation on the basis of. These approximate methods are a window function method, frequency sampling method, the best uniform approximation method. Here only to discuss the window function method. Procedure is also adopted this approach. Platform: |

(5)用三路信号s1,s2,s3尝试重新合成原始信号
4.问题:为什么重新合成的信号和原信号不相等呢?谁能解释一下?谢谢,QQ:664519036- 1. Title: Digital Filter Design and Application
2. Design requirements: use of Matlab software to composite signal separation, for example, on "Digital Signal Processing" course
Of the spectral analysis, digital filter design and signal filtering process carried out three Simulation, the simulation results.
3. Concrete steps:
(1) construct the original signal s (t)
(2) Draw s (t) of the spectrum
(3) design ellipse digital filter (IIR), including low pass, band pass, band pass, and shows amplitude-frequency characteristics
(4) filtering with a filter obtained by the isolation of three signals, observed time-domain waveform and frequency characteristics
(5) with a three-way signal s1, s2, s3 try to re-synthesis of the original signal
4. Question: Why is re-synthesized signal and the original signal is not equal to it? Who can explain? Thank you, QQ: 664519036 Platform: |
