Try these first

1. 1.

   What is noise in electronics?

   Hint

   Think about how unwanted sound interferes with music.

2. 2.

   What does EMI stand for?

   Hint

   Does it involve electricity?

3. 3.

   What does EMI stand for?

   • Electromagnetic Interference
   • Electromagnetic Induction
   • Energy Magnetic Interference

   Hint

   Consider the nature of the disturbance caused to signals.

4. 4.

   True or False: Noise has no effect on analog circuits.

   • True
   • False

   Hint

   Think of audio circuits and their quality.

5. 5.

   Explain how ground bounce can affect a microcontroller’s performance in a mixed-signal system, and propose a design improvement.

   Hint

   Consider how connections are made throughout the circuit.

6. 6.

   Design an experiment to measure the effect of switching noise on an analog signal.

   Hint

   Think about controlling your variables to get clear results.
