Correct Answer - Option 1 : Unit parabolic function
Ramp input:
It is a standard input signal that consists of a constant rate of change in input.
The ramp is a signal, which starts at a value of zero and increases linearly with time
\(r\left( t \right) = \left\{ {\begin{array}{*{20}{c}} {At;t \ge 0}\\ {0;else\;where} \end{array}} \right.\)
If amplitude A=1, it is called Unit Ramp Input.
The integration of the unit ramp is a parabolic signal
\(p\left( t \right) = \smallint t\;dt = \frac{{{t^2}}}{2}\)
A parabolic signal is expressed as
\(p\left( t \right) = \left\{ {\begin{array}{*{20}{c}} {\frac{{{t^2}}}{2};t \ge 0}\\ {0;else\;where} \end{array}} \right.\)
