The continuous time system described by 2 y(t) = x (t2) is
A. Causal, linear and time varying
B. Causal, non-linear and time varying
C. Non causal, non-linear and time-invariant
D. Non causal, linear and time-invariant
Answer:D
The continuous time system described by 2 y(t) = x (t2) is
A. Causal, linear and time varying B. Causal, non-linear and time varying C. Non causal, non-linear and time-invariant D. Non causal, linear and time-invariant
Explanation: Y (t) depends upon the future value therefore the system is anticipative and hence is not causal. But as it follows the superposition theorem so it is linear.
