Case Study: The Importance of ADC in Medical Technology

 

Medical technology relies heavily on the conversion of analogue signals to digital signals through the use of analogue-to-digital converters (ADCs). These converters help to ensure that the data collected from medical devices is accurate and can be processed by computer systems.

 

Questions:

1. What is analogue data?

2. What is digital data?

5. What is an ADC?

6. How does an ADC work?

7. What are the benefits of using an ADC in medical technology?

8. What types of medical devices require an ADC for accurate data collection?

9. How does the use of an ADC impact the accuracy of medical data?

10. What would happen if medical data was not converted from analogue to digital signals before processing?

 

Mark Scheme:

1. Analog data is continuous data that can take on any value within a certain range.

2. Digital data is a representation of data in binary form, consisting of ones and zeros.

3. The main difference between analogue and digital data is that analogue data is continuous, while digital data is discrete.

4. It is important to convert analogue data to digital data for computer processing because computers can only process digital data.

5. An ADC is an analogue-to-digital converter.

6. An ADC converts analogue signals to digital signals through the use of sampling and quantization.

7. The use of an ADC in medical technology ensures that data is accurately collected and can be processed by computer systems.

8. Medical devices such as ECG machines, MRI machines, and ultrasound machines require an ADC for accurate data collection.

9. The use of an ADC improves the accuracy of medical data by converting analogue signals to digital signals that can be processed by computers.

10. If medical data was not converted from analogue to digital signals before processing, it would not be usable by computer systems, and the accuracy of the data would be compromised.
