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 ...

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 ...

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, ...

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 ...

An oscilloscope is usually the most sensitive, and arguably most versatile, tool on a hacker’s workbench, often taking ...

Digital video is a method of representing the infinite variations of video signal levels inside a specified limit (e.g. 0mV to 700mV) as a limited number of binary numbers. Figure 1 shows a simplified ...
