Challenge Problems

Push your limits with challenges.

Question 1

Consider a real-time audio system that requires a digital filter to cancel noise while preserving signal quality. The team must select between the Impulse Invariant Method and the Bilinear Transform Method. Analyze both approaches and recommend which method you would choose based on the system's requirements.

💡 Hint: Evaluate the specific audio requirements and choose based on those needs, weighing simplicity against accuracy.

Question 2

Design a digital filter using the Bilinear Transform Method for a communication system facing high-frequency distortion. Explain how you would implement frequency pre-warping for accuracy.

💡 Hint: Focus on the formula for pre-warping and how it impacts the frequencies of interest.
