本文讲述的是Origin中的FFT中的Frequency(频率), Complex(复数), Real(实数), Imaginary(虚部), Magnitude(幅度), Amplitude(振幅), Phase(相位), Power as MSA(功率 MSA),dB的含义 首先要明确,FFT虽然名义上为Fast Fourier transform,快速傅里叶变换,但这是一个错误的命名方式,翻译时也沿用了。他计算的根本...

I am thinking of using pspectrum() or zoomFFT(). The latter seems to be more relevant to me. But after creating the object of dsp.zoomFFT(), I am not sure how to proceed because z = zfft(data(:,2)) gives me error of
I want to see FFT output in graph, but always FFT magnitude is always 0 .Can you tell the reason why it is always '0'. Actually In CCS/tools/graph there is 1.single time 2.double time 3.FFT magnitude 4.FFT magnitude and phase ...
第四步:使用np.fft.shiftfft将低频转移到中间位置 第五步:使用cv2.magnitude将实部和虚部投影到空间域 第六步:进行作图操作 importcv2importnumpy as npimportmatplotlib.pyplot as plt#第一步读取图片img = cv2.imread('lena.jpg', 0)#第二步:进行float32形式转换float32_img =np.float32(img)#第三步: 使...
Based on my understanding, when the distance between the object and the radar increases, the magnitude of the peak representing the object in the FFT decreases due to a decrease in received signal power. As a result, it becomes challenging to visualize objects (in this case, a ha...
When I plot abs(xdft) I get a magnitude of the length of the wave * amplitude /2. I am confused because I though the magnitude would be 1024*A/2. What am I missing? also since I am trying to learn fft and understand the output it spits out very well, can someone direct me to...

FFTX=FFTX(1:NumUniquePts); MX=abs(FFTX); % take magnitude of X MX=MX*2; % multiply by 2 to take into account the fact that we threw out second half of FFTX above However, the DC component of the signal is unique and shoul...
