A unit sample may be written as a difference of two steps.
8(n) = u(n) – u(n - 1)
True
False
Let y(n) be the response of a system to an arbitrary input x(n). The system
is said to be shift-invariant if, for any delay no, the response to x(n-no) is
y(n-no). A system that is not shift-invariant is said to be shift-varying.
True O
False O
