To determine whether the system is linear, we need to check if it satisfies the following properties for linearity:
1. Additivity: If the input is ( x_1(t) + x_2(t) ), the output should be ( y_1(t) + y_2(t) ).
2. Scaling: If the input is ( alpha x(t) ), the output should be ( alpha y(t) ).
In this case, the system is described by ( y(t) = x(t) ). Let's test both properties.
**Additivity Test:**
Suppose the inputs are ( x_1(t) ) and ( x_2(t) ). Then, the outputs would be ( y_1(t) = x_1(t) ) and ( y_2(t) = x_2(t) ).
Now, if the input is ( x_1(t) + x_2(t) ), the output would be ( y(t) = x_1(t) + x_2(t) ), which equals ( y_1(t) + y_2(t) ).
**Scaling Test:**
Suppose the input is ( alpha x(t) ). Then, the output would be ( y(t) = alpha x(t) ), which equals ( alpha y(t) ).
Since the system satisfies both properties, it is linear.
