Question 1
Given x[n] = 2u[n - 1] - 2u[n - 4] and h[n] = 0.5u[n] - 0.5u[n - 3], calculate the resulting y[n].
π‘ Hint: Outline the overlaps for each index of n carefully.
Question 2
Analyze what happens to y[n] when cascading two different impulse responses. For x[n]=(0.5)^n and two filters h1[n]=Ξ΄[n-1] and h2[n]=Ξ΄[n-2].
π‘ Hint: Trace the output for each filter and sum them accordingly.
