Notas de aplicación
- Improving Resolution of SAR ADCPDF, 78 Kb, Archivo publicado: jun 14, 2017
Real world parameters such as temperature, light intensity, and others are continuous in time and infinite in resolution. For digital processing, the analog signal must be converted to a digital code of fixed length, by process called �quantization’, at discrete time intervals, by a process called �sampling’. This quantization error sets the threshold beyond which the analog-to-digital converter ( - Dual Bipolar Power-Supply Considerations for AmplifiersPDF, 427 Kb, Archivo publicado: agosto 1, 2017
