Frequency estimation is a critical aspect of modern signal processing, underpinning advances in communications, radar, biomedical imaging and many other fields. At its core, this discipline seeks to ...

Microwave frequency combs offer a powerful platform for precision timing, sensing, and signal processing, but their practical use has long been ...

I designed the circuit in Figure 1 as a part of a data transmission system that has a carrier frequency of 400 kHz using on-off keying (OOK) modulation. I needed to detect the presence of the carrier ...

Oscilloscope measurement parameters provide accurate measurements of acquired waveforms. Most digital oscilloscopes offer around twenty-five standard parameters like frequency, peak-to-peak amplitude, ...

Bacteria employ complex signaling networks for adaptive gene control in changing environments. Bacterial second messenger molecules such as cyclic AMP (cAMP) relay external environmental signals into ...

Are we alone? For a moment on August 15, 1977, it certainly looked like the answer might be no. That night the Big Ear radio observatory at the Ohio State University was blasted by a remarkably ...
