Previous articles in Planet Analog make mention of the “aliasing effect.” Most EEs agree in the importance of the aliasing effect as a noise source and take for granted that anti-aliasing filters are ...

The Shannon–Hartley theorem provides a tool to quantify the information content of analog data. The theorem prescribes that unpredictability — the element of surprise — is the property that defines ...

Design linear discrete-time systems and filters and analyze their behavior. Represent continuous-time signals and linear systems in discrete time, so that such signals can be recovered in continuous ...

Wavelets provide new capabilities for analyzing real-time signals. This introductory article provides an overview and presents the basic mechanisms involved in wavelets. In many signal processing ...

Shown is a simplified continuous-time sigma-delta ADC model, comprising a sigma-delta modulator and a decimation filter. The DT-S? input structure typically implements switched capacitors, and CT-S?

This article will explain continuous-time sigma-delta (CTSD) ADC technology in a less traditional approach, enabling signal chain designers toenvision a new class of easy to use precision ADC ...
