Question

what will happen if the step value is zero​

Answer 1

Answer:

For step or impulse inputs, output will decay exponential; this is because the DC gain for this system is zero, so the total area of the impulse response must be zero. Final value of the step response is always zero; it responds to a change in the input, but sags back to zero if the input is steady.
