System represented by equation y(t) = x(t) + 3 is—
(i) Causal
(ii) Linear
(iii) Static
(iv) Time variant
The correct statements is/are—
-
- (i) only
- (i) and (ii) only
- (i) and (iii) only
- (i), (ii) and (iv) only
Correct Option: C
The given system equation
y(t) = x(t) + 3
● is causal output depends only on present and past value of the input.
● is non-linear since is constant term.
● is static since there is no integrate-differential equation.
● is time invariant since there is no time factor in the given equation.
Hence, alternative (C) is the correct choice.
