Analog and Digital Technology Part 1

What is an example of an analog measuring device mentioned in the text?

• A blood-pressure meter

• A digital thermometer

• A moving-coil meter

• A multimeter

What is the main difference between analog and digital technology?

• Analog uses numbers, while digital uses physical objects

• Analog represents information with physical representations, while digital uses numbers

• Analog is quicker, and digital is slower

• Analog is less accurate than digital
