P2.30 The measurement or sensor element in a feedback system is important to the accuracy of the system [6].

The dynamic response of the sensor is important.

Many sensor elements possess a transfer function

k H(s) = TS+1 Suppose that a position-sensing photo detector has T= 10 s. Obtain the step response of the system. Show that the step response is independent of k. Compute the time to reach 98% of the final value.
