4.1. Introduction

Try these first

1. 1.

   Define analog signals.

   Hint

   Think about how these signals can behave in a wave-like manner.

2. 2.

   What is noise coupling?

   Hint

   Consider the impact digital signals can have on sensitive components.

3. 3.

   What is a key characteristic of analog signals?

   • Discrete values
   • Continuous values
   • Binary representation
   • Digital switching

   Hint

   Recall the definition of analog signals.

4. 4.

   True or False: Digital signals are always less susceptible to noise than analog signals.

   • True
   • False

   Hint

   Think about how signals change state.

5. 5.

   Design a PCB layout that minimizes interference between analog and digital components. Detail the strategies you would use.

   Hint

   Think about separation and shielding.

6. 6.

   Discuss the implications of jitter on data conversion in mixed-signal circuits. How can designers mitigate its effects?

   Hint

   Consider what techniques minimize timing errors.
