Multiple-choice questions may continue on the next column or page – find all choices before answering. The due time is Central time. Homework 8 001 (part 1 of 3) 10 points Consider an embedded system that uses an ADC to measure a parameter called x. Which of the following terms is the smallest change in x that can be reliably detected by the measurement ? 1. Accuracy. 2. Resolution. correct 3. Measurand. 4. Precision. 5. Sensitivity. 6. Frequency response. Explanation: Let dx be the resolution of the system. If the input were to change from x to x+dx, then the system would be able to detect the change. 002 (part 2 of 3) 10 points Which of the following terms is the num- ber (n) of distinguishable input signals (x1,x2,..., xn) that can be reliably dis- tinguished from each other by the mea- surement ? 1. Sensitivity. 2. Precision. correct 3. Accuracy. 4. Frequency response. 5. Resolution. 6. Measurand. Explanation: Precision specifies the degrees of freedom from random errors. For an output signal, it is the number of different output parameters that can be produced by the system.that can be produced by the system....
