Sub-Nyquist sampling and Finite Rate of Innovation (FRI) signal processing represent a paradigm shift in the acquisition and reconstruction of signals. Traditional sampling theories require adherence ...

Digital signal processing is often a mystery to many people, but the underlying principles are fairly straightforward and within the grasp of anyone with a technical background. In this feature, we’ll ...

The market for audio applications and devices has significantly grown over the last couple of years. Applications such as smart speakers, Bluetooth speakers, smartphones, and voice-controlled ...

An analog-to-digital converter (ADC) sampling rate is determined by a clock signal that controls how often a voltage snapshot is taken for each conversion. However, clock signal timing isn’t perfect, ...

While many broadcast engineers would be delighted to have a digital oscilloscope with a 1 GHz sampling rate, researchers developing defenses against energy pulse weapons and scientists studying ...

A signal chain consists of several components, such as amplifiers, data converters, interface, clocks and timing. The purpose of the signal chain is to gather and process data or apply system controls ...

Although Arbs eventually may become the ultimate RF generators, today many RF applications can be addressed using the latest instruments. Arbitrary waveform generators (Arbs) are among the most ...

Over the past decades, the high-speed analog-to-digital converter (ADC) performance metric that mattered to most has changed, albeit slowly. Primarily as a result of signal acquisition systems’ ever ...
