Question 1.
What is median filtering used for?
Show hintHide hint
Think about how the median value can provide a better representation of a set of numbers.
Question 2.
What does Wiener filtering minimize?
Show hintHide hint
Consider the implications of accuracy in signal processing.
3Question 3.
What is the primary function of Wiener filtering?
- To increase signal amplitude
- To remove all signals
- To minimize noise error
Show hintHide hint
Think about how we can make estimates more accurate.
4Question 4.
True or False: Median filtering works best for removing Gaussian noise.
- True
- False
Show hintHide hint
Consider the types of noise commonly encountered in signals.
Question 5.
Consider an audio signal disturbed by random noise. Describe how you would use both median and Wiener filtering to enhance the signal. What advantages does each bring?
Show hintHide hint
Think about the nature of the noise and how each filtering technique addresses it.
Question 6.
Using MATLAB, create a functional code snippet for real-time audio denoising utilizing both median and Wiener filters. Explain your choice of parameters.
Show hintHide hint
Consider the balance between timing and filter effectiveness for real-time processing.
