Answer:
True
Step-by-step explanation:
In control systems, a system is said to have "memory" if the output at time t₁, namely y(t₁) depends not only on the input at time t₁ (u(t₁)), but also on the input for times t>t₁. This means that the system's output at a given time depends on the past inputs over a range of times, indicating the presence of memory in the system's behavior.
