9.1. Introduction

Try these first

1. 1.

   Define noise in the context of electronic systems.

   Hint

   Think about sounds that distract you while you are listening.

2. 2.

   What is a mixed signal circuit?

   Hint

   Consider the terms 'analog' and 'digital'.

3. 3.

   What is the primary effect of noise on mixed signal circuits?

   • It enhances performance
   • It disrupts signal integrity
   • It is generally beneficial

   Hint

   Think about what happens when noise increases.

4. 4.

   True or False: Noise is beneficial for electronic systems.

   • True
   • False

   Hint

   Recall the definition and purpose of noise.

5. 5.

   Assess how thermal noise varies with temperature in a resistor and its implications on a mixed signal circuit.

   Hint

   Consider the relationship between temperature and electron behavior.

6. 6.

   Evaluate the impact of failure to control shot noise in a high-speed data acquisition system.

   Hint

   Think about how current fluctuations can alter readings.
