The true statements for the system given below
y′(t + 4) + 2y(t) = x(t + 2)
-
- dynamic and causal
- time-invariant and non-causal
- dynamic and non-causal
- time-invariant and causal
Correct Option: A
Given system y′(t + 4) + 2y(t) = x(t + 2) is causal and dynamic.
Causal: Since, output dependes upon the present and past input only.
Dynamic: Because input and output arguments are different.
