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 ...
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 ...
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?
