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 ...

Sound can be represented with both analog or digital audio signals. Analog audio signals use electrical voltage levels. Different types of transducers convert sound to electrical signals and ...

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 ...

For many scientific experiments, today’s researchers require a precise reference frequency that allows them to calibrate the time measurements made by their equipment. Such experiments include ...

Researchers developed a method to enable quantum sensors to detect any arbitrary frequency, with no loss of their ability to measure nanometer-scale features. Quantum sensors detect the most minute ...

The disc-shaped resonator measures less than 2 centimeters across, yet the innocuous device is eavesdropping on spacetime. It’s a newly built acoustic wave resonator, and in its first 153 days of ...

Why are more precision applications adopting CTSD ADCs? How do CTSD ADCs simplify the signal chain? Steps for choosing and interfacing with the right ADC. CTSD vs. DTSD technology. 2. A compact size ...
