3.4.1. Definition

Try these first

1. 1.

   What does ADC stand for?

   Hint

   Remember, it takes an analog signal and makes it digital.

2. 2.

   What is the purpose of a DAC?

   Hint

   Think about how you hear sound from a computer.

3. 3.

   What does an ADC do?

   • Converts digital to analog
   • Converts analog to digital
   • Filters signals

   Hint

   Think about how sound is recorded digitally.

4. 4.

   True or False: DACs are used in audio playback systems.

   • True
   • False

   Hint

   Consider how we hear music from a digital device.

5. 5.

   You have a 10-bit ADC. What is the smallest voltage increment it can detect if its input range is from 0V to 5V?

   Hint

   Consider dividing the total range by the number of possible levels.

6. 6.

   Given a signal processed by a DAC, the output settles to a new value after 500 microseconds. Suggest ways to improve the settling time.

   Hint

   Think about how components in the circuit influence overall performance.
