2.3.2. Decomposition of Systems

Try these first

1. 1.

   What does signal amplification do?

   Hint

   Think about how a microphone works.

2. 2.

   Define 'gain' in relation to analog circuits.

   Hint

   Consider what happens to your voice with a loudspeaker.

3. 3.

   What does an amplifier do?

   • Increases signal strength
   • Decreases signal strength
   • Modifies the signal shape

   Hint

   Think about the function of audio amplifiers.

4. 4.

   True or False: Linearity in circuits is optional.

   • True
   • False

   Hint

   Consider the importance of clear sound in music.

5. 5.

   An audio engineer wants to design a circuit to amplify weak musical signals while filtering out background noise. What types of circuits and components might they use?

   Hint

   Think about how a concert sound system works with microphones.

6. 6.

   How would you visualize the difference between linear and non-linear amplification? Construct an example using simple signals.

   Hint

   Use sine waves for linear and square waves for non-linear examples.
