Ultrashort pulses play a significant role in spectroscopic applications. Their broad spectral bandwidth enables simultaneous characterization of the sample at various frequencies, eliminating the need ...

In part 1, we started to make some intuitive connections between near-Nyquist sampling, the addition of close-frequency sines, and how those signals would interact with perfect LP filters. Let's put ...

Nyquist-sampling theory lies at the heart of today's digital-communications systems. It requires that data-conversion systems include antialiasing input filters. Designers need to understand the ...

Direct conversion, or zero IF, receivers are popular in applications where the need to reduce power consumption, reduce costs and extend battery life are behind requests to use 'all the Nyquist ...

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 ...
