Question
Find out the integrating type analog to the digital converter?
- Tracking converter
- Dual slope ADC
- Counter type converter
- Flash type converter
Solution
The integrating type analog to digital converter is the Dual slope ADC.
Here's a step by step explanation:
-
The dual slope ADC is called integrating type because it uses an integrator to convert the input voltage into time or frequency, which can then be easily digitized.
-
The process starts by resetting the integrator and then input voltage is applied. The output of the integrator increases linearly as long as the input voltage is applied.
-
After a fixed time period, a known reference voltage of opposite polarity is applied to the integrator. The output of the integrator decreases and eventually becomes zero.
-
The time taken for the output to become zero is measured and is proportional to the magnitude of the input voltage. This time period is then converted into digital form.
-
Therefore, the dual slope ADC is the integrating type analog to digital converter.
