When working on a recent Design Idea for an adjustable filter, I wanted to use an electrical noise source to generate an FFT spectrum graph on my oscilloscope. To set up the test, I reached for my ...
At first glance, the link between an SUV and a Formula E electric single-seater isn’t obvious. However, behind the comfort, silence and refinement we’ve come to expect from DS Automobiles lies another ...
PFFFT does 1D Fast Fourier Transforms, of single precision real and complex vectors. It tries do it fast, it tries to be correct, and it tries to be small. Computations do take advantage of ...
Abstract: The inverse synthetic aperture radar (ISAR) imaging for nonuniformly rotating target has always been a challenging task due to the time-varying Doppler parameter, especially in the low ...
The Discrete Fourier Transform (DFT) converts N time-domain samples into N frequency-domain coefficients, revealing the spectral content of a signal. The naive DFT requires O(N²) complex ...
This requires an algorithm: students are taught to stack one number atop another and multiply each digit of the bottom number ...
Three heads are better than one. Versions of this proverb are found worldwide and throughout history. Yet in the race to ...

New computational method combines modern density functional with adaptive algorithm to predict semiconductor properties
Semiconductors are central to modern technology. They are used in computer chips, solar cells, sensors, LEDs and ...
Abstract: This paper describes a class of multibeam synthesis algorithms that are useful for large arrays when simultaneous nulling of interference is required. In these algorithms, the computational ...
Atrial fibrillation (AF) is the most common heart rhythm disturbance and is associated with substantial morbidity and mortality. The overall prevalence of AF varies from 2% to 5% of the general ...
