4.2.1. Noise Coupling

Try these first

1. 1.

   What is noise coupling?

   Hint

   Think about how digital signals behave.

2. 2.

   Name one component that can suffer from noise coupling.

   Hint

   Consider components dealing with analog signals.

3. 3.

   What causes noise coupling in a mixed-signal design?

   • Low battery level
   • Digital switching
   • Analog signal processing

   Hint

   Consider what happens during a digital signal transition.

4. 4.

   True or False: Analog circuits can generally tolerate high-frequency noise without performance issues.

   • True
   • False

   Hint

   Consider the nature of analog signals.

5. 5.

   Design a mixed-signal PCB layout that minimizes noise coupling between digital and analog circuits. Mention at least three techniques you would employ.

   Hint

   Think about how physical distances and barriers can affect signal relationships.

6. 6.

   Evaluate a scenario where a malfunctioning ADC is observed in a mixed-signal system. Discuss potential causes and solutions related to noise coupling.

   Hint

   Consider both the electric layout and physical component arrangements.
