Design an LTI system that translates an input signal into an output where the peak value is cut in half and then shifted by 2 units to the right. Explain how you would account for linearity and time-invariance.
💡 Hint: Think about how you would change the input signal mathematically before analysis!
Discuss a real-world scenario in which an LTI system approximation might fail and the implications this has on predictions.
💡 Hint: Consider audio engineering principles and how they deviate with extremes.
