Noise Propagation in Multiple-Input ADC-Based Measurement Systems

ADC Requirements for RTD Temperature Measurement Systems

Visit analog.com There are several types of temperature sensors that can be used in a temperature system. The temperature sensor to use depends on the temperature range being measured and the accuracy required. Along with the sensor, the accuracy of the temperature system depends on the performance of the analog-to-digital converter (ADC) to which the sensor is interfaced. A high resolution ADC...

State Estimation with Unknown Input and Measurement Noise Reconstruction Based on Descriptor Systems

-The paper considers the problems of state estimation, unknown input and measurement disturbance reconstruction for a class of Lipschitz nonlinear system. By taking the measurement disturbance vector as an extended state vector, the original system is transformed into an augmented descriptor system. For the descriptor system, the necessary and sufficient condition of the existence of the unknow...

Noise floor in ADC testing

Noise floor is a frequency spectrum parameter that is widely used in ADC testing although it has not been properly defined and described by a formula in any ADC standards yet. IEEE Std 1057-1994 does not mention the noise floor but it generally uses noise or noise level that is not defined. IEEE Std 12412000 provides a formula for noise floor computation depending on the number of ADC bits; con...

Examining Emergent Dominance Patterns in Multiple Input Based Educational Systems

Past work with multiple input devices in low resource educational environments has largely been motivated by patterns of dominance that emerge when a large group of students is asked to share a single computer — inevitably, some students, at the cost of others, derive higher value out of the experience. Conversely, concern has been expressed about the lack of social learning and collaboration t...
