It would be if your time is measured in seconds. 댓글 수: 2 Star Strider2016년 5월 23일 Shoji Ina’s ‘Answer’ moved here: As my question, acceleration was measued by sec. I wanted to know whether I need to square the FFT Spectrum Estimate provided by sptool_FFT analyze ...
Modern spectrum analyzers have a high degree of capability. As most use digital techniques, not only is the signal processing accomplished using digital signal processing using Fast Fourier Analysis, FFT, but also the front panel controls and display are controlled using a control processor. This ...
A spectrogram is a graph that displays the strength of a signal over time for a given frequency range. Using a color spectrum, it points to the frequencies where the signal’s energy is highest and shows the energy variation over time. For a vibration signal, a spectrogram’s color scale ...

A spectrum analyzer is a device that measures and displayssignalamplitude (strength) as it varies by frequency within its frequency range (spectrum). The frequency appears on the horizontal (X) axis, and the amplitude is displayed on the vertical (Y) axis. It looks like anoscilloscope, and ...
spectrum with only one peak at the frequency that I'm interested in, which is what I'm supposed to obtain by the way. Now the question is, and it's a question that probably comes from my low understanding of FFT, is the FFT peak amplitude supposed to be the same value as...

In this picture i am having an original signal as well as reconstructed signal from EEMD method and i have done fft of both, but i am getting peaks at same frequency but in different amplitude...what is the physical significance of higher amplitude in fft...
You can perform spectrum measurements, demodulation, and signal analysis with a PXI vector signal analyzer (VSA), which can measure the magnitude and phase of an input signal at a certain frequency within a specified bandwidth.
An autopower spectrum, measured with a 1 Hz resolution and a bandwidth of 6000 Hz, would have 6000 data points or spectral lines as shown inEquation 1. Equation 1: The number of spectral lines is determined by dividing the bandwidth by the frequency resolution. ...
