8.2.3. Noise Reduction and Signal Enhancement

Try these first

1. 1.

   What is the purpose of a moving average in signal processing?

   Hint

   Think about averaging values over time.

2. 2.

   What is a Kalman filter used for?

   Hint

   It involves using measurements over time.

3. 3.

   What is the primary function of a moving average in noise reduction?

   • To increase noise
   • To decrease fluctuations
   • To amplify signals

   Hint

   Think about how averaging works.

4. 4.

   Kalman filters are optimal in what type of systems?

   • True
   • False

   Hint

   Consider their usage in real-time applications.

5. 5.

   Propose a new application for adaptive filtering in a field not discussed in class. Discuss the potential benefits and challenges.

   Hint

   Consider fields where conditions are unpredictable.

6. 6.

   Calculate the output of a moving average filter with a set of noisy data: [1, 5, 3, 8, 2] with a window size of 3.

   Hint

   Don't forget to sum and average the appropriate range!
