Electronics-Analog and Digital Converts
11. Which is not an analog-to-digital (ADC) conversion error?
- differential nonlinearity
- missing code
- incorrect code
- offset
12. Sample-and-hold circuits in analog-to digital converters (ADCs) are designed to:
- sample and hold the output of the binary counter during the conversion process
- stabilize the comparator's threshold voltage during the conversion process
- stabilize the input analog signal during the conversion process
- sample and hold the D/A converter staircase waveform during the conversion process
13. A sample-and-hold circuit samples an analog value and holds it long enough for the analog-to-digital conversion to occur.
- TRUE
- FALSE
14. Incorrect codes are a form of output error for a digital-to-analog converter (DAC).
- TRUE
- FALSE
15. If we double the number of bits in our digital representation of a number from 4 to 8 bits, we double the relative accuracy of the conversion from digital to analog.
- TRUE
- FALSE
16. The flash method of analog-to-digital conversion (ADC) uses comparators that compare reference voltages with the analog input voltage.
- TRUE
- FALSE
17. A digital-to-analog converter (DAC) is said to be nonmonotonic if the magnitude of the output voltage increases every time the input code increases.
- TRUE
- FALSE
18. The relative accuracy of a digital-to-analog converter (DAC) is determined by settling time.
- TRUE
- FALSE
19. The key advantage of the successive approximation analog-to-digital converter (ADC) is its conversion speed.
- TRUE
- FALSE
20. One way to determine the resolution of a digital-to-analog converter (DAC) is to compare the ratio of one step voltage to the maximum output voltage.
- TRUE
- FALSE
