Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

An audio system has a mid-range amplifier whose gain significantly drops when frequency extends over 5 kHz. It delivers clear sound up to that point. Explain what filter type this amplifier represents and the implications.

💡 Hint: Think about the role of cutoff frequencies.

Challenge 2 Hard

An engineer finds that an analog circuit exhibits a nonlinear characteristic after exceeding certain input levels. Discuss the potential solutions to avoid distortion in further applications.

💡 Hint: Consider approaches used in maintaining signal clarity.
