Many serious machine problems can be diagnosed early with normal vibration analysis techniques based on fast Fourier transforms. But some problems remain dangerously hidden in the vibration reading — ...

RF signals historically are measured using spectrum analyzers, at least that was before oscilloscopes offered sufficient bandwidth for those measurements. With oscilloscope bandwidths over 100 GHz, RF ...

Trace gas sensors are used in different fields. Light-induced thermoelastic spectroscopy (LITES) has extremely high sensitivity and offers non-contact measurement, attracting extensive research ...

[brmarcum] takes us back to analog building block basics with his Frequency Modulation and Demodulation tutorial. Frequency Modulation (FM) sounds simple at first, but understanding the electronics ...

Computational fluorescence microscopy (CFM) requires accurate point spread function (PSF) characterization for high-quality imaging. We propose a sample prior–based PSF decoupling method, where ...

This article investigates the demodulation capabilities of a DSSSsuper-regenerative receiver. Starting from the general expressionthat characterizes the receiver's behavior, we demonstrate that afew ...

Researchers have reported a sample-prior-based approach to point spread function decoupling that improves system ...
