Digital instruments sample analog waveforms and operate on the samples with the assurance that the data can be restored to continuous analog form. The sampling theorem states that a signal digitized ...

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 ...

An arbitrary waveform generator (Arb) can be seen as a reversed version of a real-time DSO. Both instrument categories share the same theoretical principles applied to sampled signals. There are, ...

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 ...

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 ...

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 ...
