Explanation: Since the integrating type ADC do not require sample and hold circuit at the input. The change in input during conversion will not affect the output code and is proportional to the value of the input averaged over the integration period. 5. Which type of ADC is chosen for noisy environment?
A. Successive approximation ADC
B. Dual slope
C. Charge balancing ADC
D. All of the mentioned
Answer:A

Which type of ADC is chosen for noisy environment?
A. Successive approximation ADC B. Dual slope C. Charge balancing ADC D. All of the mentioned
Explanation: The main advantage of these converters is that it is possible to transmit frequency even in noisy environment or in isolated form. 6. How to overcome the drawback of the charge balancing ADC?
