b) Less than 100 µs
c) Less than 500 µs
d) Greater than 1000 µs
View Answer
Explanation: Typical conversion speed of ADC is between 1µs and 100 µs.
2. Which of the following type output is provided by ADC?
a) Serial type
b) Parallel type
c) Both serial and parallel type
d) None of the mentioned
View Answer
Explanation: ADC provides both serial and parallel type output according to application.
3. Which of the following method is employed for ADC?
a) Ladder network
b) Successive approximation type
c) PWM type
d) None of the mentioned
View Answer
Explanation: In successive approximation method input value is constantly compared with a reference value.
4. Successive approximation is slow for large bit application.
a) True
b) False
View Answer
Explanation: Successive approximation method is much faster in large bit application.
5. Which of the following represents range of frequency measured by ADC?
a) Bandwidth
b) Threshold frequency
c) Peak frequency
d) None of the mentioned
View Answer
Explanation: Bandwidth of ADC is the maximum range of frequency measured by ADC.
6. Dynamic range of ADC is depended on _______________
a) Resolution
b) Linearity
c) Accuracy
d) All of the mentioned
View Answer
Explanation: Dynamic range of ADC is depended on both resolution, linearity and accuracy.
7. Small timing errors in ADC additional to noise is known as ____________
a) Jitter
b) Aliasing
c) Super noise
d) None of the mentioned
View Answer
Explanation: Jitter is a type of noise that is produced additional to noise.
8. ENOB in ADC stand for _________________
a) Effective number of bytes
b) Effective number of bits
c) Effective nibble baud
d) None of the mentioned
View Answer
Explanation: Effective number of bits (ENOB) represents the number of bits measured by ADC.
9. ENOB is a negation of resolution.
a) True
b) False
View Answer
Explanation: ENOB or effective number of bits is the number of bits measured by ADC and it is equal to resolution.
