Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a low-pass FIR filter for an audio application where you need to retain frequencies below 500 Hz while removing noise above 2000 Hz. Explain each step you would take in the design process.

💡 Hint: Start with identifying the signal properties.

Challenge 2 Hard

Analyze the frequency response of a hypothetical FIR filter. If the filter length N is increased from 5 to 15, describe the expected changes in the frequency response and performance.

💡 Hint: Consider how the filter length interacts with frequency components.
