A pure integrator is represented by 1/s. This is only the start of this problem though. Just because the "transfer function" has s's in it, doesn't necessarily mean it is the proper function to be assessing the "number" of the system. Is the the function for the forward, open loop, or system?

Based on the operational amplifier (op-amp), it performs the mathematical operation of integration with respect to time; that is, its output voltage is proportional to the input voltage integrated over time. Response to Sinusoidal Input. The sinusoidal response of a system refers to its response to a sinusoidal input: u(t) = cos ω0t or u(t) = sinω0t. To characterize the sinusoidal response, we may assume a complex exponential input of the form: u(t) = ejω0t, u(s) = 1 s − jω0.
