Editor's note: I am happy to bring you, my friend and former long-time colleague at Texas Instruments, Matthias Feulner, one of the best high-speed communications experts in the industry The latest ...

A digital scope’s effective bandwidth of isn’t determined merely by analog componentsthe digitizer and memory also play a role When selecting an oscilloscope for a specific measurement, the first ...

When evaluating the dynamic performance of precision analog-to-digital converters (ADCs) using fast Fourier transform (FFT) analysis, coherent sampling typically is used to accurately measure the ...

Analog measurement resources in today’s mixed-signal ATE use ADCs, and the test methodologies are based on DSP. Two types of measurement resources are distinguished by the relationship of the test ...

Suppose you take a few measurements of a time-varying signal. Let’s say for concreteness that you have a microcontroller that reads some voltage 100 times per second. Collecting a bunch of data points ...

Output 22.5.8 displays the predicted response functions and Output 22.5.9 displays predicted cell frequencies (from the PRED=FREQ option), but since the model does not fit, these should be ignored.

PROC FREQ is used primarily to investigate the relationship between two variables; any confounding variables are taken into account by stratification rather than by parameter estimation. PROC CATMOD ...

Software radio is the technique of getting code as close to the antenna as possible. It turns radio hardware problems into software problems. The fundamental characteristic of software radio is that ...
