Challenge Problems
Push your limits with challenges.
Question 1
Consider a signal defined as f(t) = e^(-t) * u(t), where u(t) is the unit step function. Calculate the output of a system whose impulse response is given by delta(t) under this signal input.
💡 Hint: Focus on the definition of the system's impulse response.
Question 2
How would the output differ if the impulse response of the system were the derivative of the delta function instead of the delta function itself?
💡 Hint: Remember the property of differentiation in relation to impulse responses.
