Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given the second-order difference equation 2y[n] - 3y[n-1] + y[n-2] = x[n] with initial conditions y[-1]=2 and y[-2]=3, solve for y[n] using the Z-Transform.

💡 Hint: Ensure all transformations track the specified initial conditions!

Challenge 2 Hard

Discuss the implications of failing to use the unilateral Z-Transform when initial conditions are present in a given difference equation.

💡 Hint: Reflect on how initial conditions impact calculations!
