8.2.4. Analog Preprocessing

Try these first

1. 1.

   What is the purpose of signal conditioning?

   Hint

   Think about what happens before digitization.

2. 2.

   Name one method used in signal conditioning.

   Hint

   It's about increasing signal strength.

3. 3.

   What does signal conditioning aim to achieve?

   • A. Improve digital audio quality
   • B. Prepare analog signals for ADC
   • C. Increase noise in signals

   Hint

   Consider the purpose of preparing signals before they are digitized.

4. 4.

   True or False: Level shifting adjusts the amplitude of a signal.

   • True
   • False

   Hint

   Think about what level shifting entails.

5. 5.

   Design a simple analog preprocessing system for an ECG application focusing on the steps needed for signal conditioning.

   Hint

   Consider each step’s purpose when designing your system.

6. 6.

   Evaluate the impact of insufficient amplification in an analog preprocessing chain in a communication system.

   Hint

   Reflect on the consequences of weak signals in digital communication.
