Challenge Problems
Push your limits with challenges.
Question 1
A periodic square wave has a frequency of 1 kHz. If passed through a high-pass filter with a cutoff frequency of 500 Hz, describe how the output would differ from the input.
💡 Hint: Consider the harmonic components that would be filtered out.
Question 2
Given a periodic signal represented by a Fourier series, explain how you would implement a low-pass filter in the frequency domain.
💡 Hint: Think about how frequency responses affect individual harmonic contributions.
