- For the successive approximation ADC, the conversion time is proportional to the input voltage range, so for a 6V input signal, the conversion time will be 2 times Ta. Therefore, the approximate time taken by the successive approximation ADC for a 6V input signal will be 2Ta.
- For the single slope integrating ADC, the conversion time is also proportional to the input voltage range, so for a 6V input signal, the conversion time will be 2 times Tb. Therefore, the approximate time taken by the single slope integrating ADC for a 6V input signal will be Tb.
- Therefore, the approximate time taken by the two ADCs for a 6V input signal will be 2Ta for the successive approximation ADC and Tb for the single slope integrating ADC.

Understanding ADC Types
Two types of ADCs are considered here: successive approximation and single slope integrating.
Successive Approximation ADC
- This type of ADC converts the analog signal by comparing it to a reference voltage in a stepwise manner.
- The time taken (Ta) is consistent and primarily depends on the number of bits.
- For a 10-bit ADC, it takes Ta to convert a 3V signal.
Single Slope Integrating ADC
- This ADC integrates the input signal over time and then measures the time taken to discharge.
- The time taken (Tb) is directly proportional to the amplitude of the input voltage.
- For a 3V signal, it takes Tb.
Effect of Increasing Voltage
When the input voltage is increased to 6V:
For the Successive Approximation ADC:
- The time taken remains the same (Ta) because the time for conversion is not affected by the amplitude of the input signal.
For the Single Slope Integrating ADC:
- The time required is proportional to the voltage. Doubling the input voltage from 3V to 6V will approximately double the conversion time.
- Therefore, it takes 2Tb for a 6V signal.
Conclusion
Thus, for the increased input signal of 6V:
- Successive Approximation ADC takes approximately Ta.
- Single Slope Integrating ADC takes approximately 2Tb.
Hence, the correct answer is option 'D' (2Ta, Tb).
