As we discussed at the beginning of this series, sampling has nothing to do with digitization, or quantization. A sampled signal can remain in the analog domain, though digitized signals are sampled ...

Digital signal processing is often a mystery to many people, but the underlying principles are fairly straightforward and within the grasp of anyone with a technical background. In this feature, we’ll ...

A block diagram of a typical sampled data DSP system is shown in Figure 2-1. Prior to the actual analog-to-digital conversion, the analog signal usually passes through some sort of signal conditioning ...

Sample rates for analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) continue to evolve, now reaching 5 Gsamples/s at 10-bit resolutions and 1.5 Gsamples/s at 12 bits. These ...

When working with mixed-signal technology, you will find that the subject of dithering keeps showing up. Most engineers know that averaging “n” samples of an analog-to-digital converter (ADC) will ...
