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 ...

The need for high-frequency semiconductor devices is surging, fueled by growing demand for advanced telecommunications, faster sensors, and increasingly autonomous vehicles. The advent of ...

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 ...

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 ...
