Question 1
Design a causal system with an impulse response h(t) that includes both exponential decay and a constant offset. Describe how this system operates.
💡 Hint: Think about how both terms contribute to the overall system behavior.
Question 2
Given the impulse response h(t) = sin(t)u(t), determine whether the system is causal or not and explain your reasoning.
💡 Hint: Analyze the behavior of the sine function under the unit step function.
