3.3.1. Definition

Try these first

1. 1.

   What does DAC stand for?

   Hint

   Think about what it converts.

2. 2.

   List one application of a DAC.

   Hint

   What have we discussed in class?

3. 3.

   What is the main function of a DAC?

   • Convert analog to digital signals
   • Convert digital to analog signals
   • Store digital signals
   • None of the above

   Hint

   What is the word 'convert' indicating here?

4. 4.

   True or False: The higher the resolution of a DAC, the fewer levels it can generate.

   • True
   • False

   Hint

   Think about how many bits allow distinct levels for output.

5. 5.

   Given a DAC with a resolution of 12 bits, calculate how many distinct levels it can produce.

   Hint

   Think about the power of two for each bit.

6. 6.

   If a DAC has a glitch impulse that affects audio quality, discuss methods to minimize this issue in design.

   Hint

   Consider ways in which signals can be smoothed reducing sharp transitions.
