Challenge Problems
Push your limits with challenges.
Question 1
Evaluate the convolution of a square wave defined as x[n] = 1 for 0 <= n < 5 and h[n] = Ξ΄[n-2] + Ξ΄[n-3]. What is the resulting output signal?
π‘ Hint: Use the convolution sum definitions to derive the outputs step by step.
Question 2
Provide a detailed analysis of how the output signal changes when a sinusoidal input x[n] = sin(Οn) is convolved with an impulse response h[n] = e^{-an}u[n].
π‘ Hint: Recall the nature of convolution as overlapping influence of each segment.
