The converter as a black box
A/D and D/A converters are the link between the analog world of transducers and the digital world of signal processing and data handling. In an analog system bandwidth is limited by device and element performance and by the parasitics introduced. Thermal noise generated in active and passive components limits the dynamic range of an analog system. The ratio between the maximum allowable analog signal and the noise determines the dynamic range of the system. The signal-to-noise (S/N) ratio is a measure of the maximum dynamic range.
