Question 1

What does an adaptive filter do?

Adjusts its coefficients based on the input signal
Looks for fixed patterns in the input
Predicts without learning

💡 Hint: Remember the key function that distinguishes adaptive filters.

Question 2

True or False: The error signal is used to guide the adjustment of the filter's coefficients.

True
False

💡 Hint: Think about how feedback is essential in learning systems.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Using the formula for predicted output, create a scenario where past data samples could be used to predict the next 5 samples of a signal.

💡 Hint: Think about how each coefficient might weigh past samples differently.

Challenge 2 Hard

Imagine a scenario in an echo cancellation system. If the desired output is known, how can you iterate to improve prediction accuracy using error signal?

💡 Hint: Consider each step as finding a way to 'listen' better to the current environment.
