Design engineers don't always need scopes whose capabilities go way beyond the ordinary. Many design-lab benches can do with instruments whose bandwidth is measured not in gigahertz but in hundreds or ...
Bad Fast Fourier Transfer (FFT) data captures can cause you to misunderstand the true performance of your analog-to-digital converter (ADC). Some engineers like to coherently sample and capture data ...
A new algorithm performs Fourier transforms using a minimal number of samples. The fast Fourier transform, one of the most important algorithms of the 20th century, revolutionized signal processing.
SIAM Journal on Numerical Analysis, Vol. 55, No. 6 (2017), pp. 2540-2564 (25 pages) This article considers the use of total variation minimization for the recovery of a superposition of point sources ...
Specifications for analog-to-digital converters (ADCs) often include a fast Fourier transform (FFT) plot, such as the one shown in the figure, for a 12-bit ADC with a single-frequency input signal. In ...
When James Cooley and John Tukey introduced the Fast Fourier transform in 1965, it revolutionized signal processing and set us on course to an array of technological breakthroughs. But today’s ...
What is The Goertzel Algorithm? The Goertzel algorithm can perform tone detection using much less CPU horsepower than the Fast Fourier Transform, but many engineers have never heard of it. This ...
Analog measurement resources in today’s mixed-signal ATE use ADCs, and the test methodologies are based on DSP. Two types of measurement resources are distinguished by the relationship of the test ...
With a good DSA, analyzing the sound of one hand clapping is not a problem. A dynamic signal analyzer (DSA) is used to investigate signals representing forces and motions. In this context, the word ...
