I am trying to get the frequency response of a speaker by playing a 20Hz to 20KHz chirp through the speaker and comparing the speaker output sound file to the original input sound file. This is what I have so far but the plot doesn't look like I expect. The Y-axis does not seem...

I have an excel file of FFT data including frequency, amplitude and phase of a bearing signal. I want to montitor the condition of the bearing using elvelope method. How can i plot x-t of the signal and also find envelope of this signal?
I have done a code to obtain the FFT of an audio recorded with Matlab. I'm getting my result in amplitude but I'd like to get it in dB in the frequency domain... Could someone please help me? Here is my code and my curves: ...

In fact, the cover story explains how all the devices—FPGAs, 3D ICs and MPSoCs—in the new UltraScale+ portfolio attain at a minimum twice the performance per watt of pre- ceding-generation systems, thanks to implementation in TSMC's 16nm FFT+ process. Additional performance/watt benefits ...
In MATLAB R2018b there is not a way to directly export the FFT analysis from the graphical interface opened from the Powergui block.The workaround is to use command line tools to obtain the desired data in the base workspace: 1. Get initial default s...
Line spread function(LSF) is the derivative of the linear edge profile. MTF is the fast fourier transform (FFT) of the LSF. When LSF is selected, LSF variance (σ2), which is proportional to theDxO blur unit, is displayed. Edge pixel profileis proportional to the edge profile in pixels...
Learn how to perform a sensitivity analysis in COMSOL Multiphysics®, which can show you how certain parameters will affect the performance of your design.
Has the nufftn been tested with fully sampled data sets, and shown to be equivalent to the fft functions? Is there a location where Matlab provides access to verification code or results? There is some sample code here and on thenufftnhelp page, but...
