Signal Chain Basics #160: Making sense of coherent and noncoherent sampling in data-converter testing

Bad Fast Fourier Transfer (FFT) data captures can cause you to misunderstand the true performance of your analog-to-digital converter (ADC). Some engineers like to coherently sample and capture data ...

Capturing and Evaluating High-Frequency Signals

Coherent interleaved sampling is a new technique that can acquire data faster with more data points than sequential sampling. Engineers who need to characterize semiconductor devices, high-speed ...

Choosing the right FFT window function while testing ADCs

Analog-to-digital converters (ADCs) are essential building blocks in modern electronic systems. They form the critical link between front-end analog transducers and back-end digital computers that can ...

Erratum: Coherent sampling of active mode-locked terahertz quantum cascade lasers and frequency synthesis

In the version of this Article originally published, the x-axis scales in Fig. 5g–i were incorrect. This error has been corrected in the HTML and PDF versions of ...
