Q1:

The following system which is static is __________ .

A

B

C y(t) = x(n - 1)

D y(t) = ex(t)

ANS:D - y(t) = ex(t)

The system represented by expression ex(t) is static (memoryless) ∵ output at time = 't' dependent only. In case of derivative, if we take the laplace transform we have to consider initial conditions. Hence memory is required.
