I'm reading WAV file data using a class from the soundstretch library which returns PCM samples as floats, then performing FFT on those samples with the fftw3 library. Then for each frequency (rounded to the nearest KHz), I am totalling up the amplitude for that frequency. So for a low...

We will answer these questions using the 18+ years of available Smart Beta factor returns. Below are the Smart Beta single factor indexes covered in the following analysis: How Did the Factors Perform Over Time? Similar to what the majority of industry practitioners and academic researchers have ...
Hi, I want to get peak performance using batch FFT. I am giving sample code below that i have written. I have compiled on host using command icc -mkl
It enables maintenance engineers to set a maintenance strategy and perform it effectively and efficiently. Conclusion FFT spectrum analysis is a very important technique for the interpretation of the vibration signal and is often used to detect imbalance and misalignment. In practice Machine Condition ...
The separation between closely located fields is no longer possible, and you can observe that strictly using Nyquist-Shannon sampling theorem to determine the pixel-limited resolution is not sufficient. The vertical separation between the field pairs is 6.25 um in the object plane (Figure 9) and ...
Noncontinuous or abrupt transitions in the output frequency may lead to unwanted spurious content during fast Fourier transform (FFT) analysis. Figure 2 shows an example of continuous frequency hopping, where the selected source switches from NCO0 (programmed to F1) to NCO1 (programmed to F2). ...
