Explanation: Charge balancing ADC depend up on RC product whose value cannot be easily maintained with temperature and time. This is eliminated using dual slope ADC as it is independent of R, C and T. 7. Which among the following has long conversion time?
A. Servo converter
B. Dual ramp converter
C. Flash converter
D. None of the mentioned
Answer:A

A. Servo converter B. Dual ramp converter C. Flash converter D. None of the mentioned
Explanation: The main disadvantage of dual slope ADC is the long conversion time. For instance, if 2n-T=1/50 is used to reject line pick-up, the conversion time will be 20ms. 8. In which application dual slop converter are used.
