Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a simple low-pass filter with a specified cutoff frequency of 1 kHz. Explain how you would determine the filter type and impulse response.

💡 Hint: Consider different filter designs and how they shape the frequency response.

Challenge 2 Hard

If you convolve a signal with a low-pass filter, what changes do you expect to see in the output signal?

💡 Hint: Visualize how convolution modifies the sharp changes in the signal.
