Question: the rotating speed of a variable speed motor is measured...

Question details

The rotating speed of a variable speed motor is measured by a speed sensor (optical encoder). The signal from this sensor can be used to compute the rotating speed from the time period T displayed by an oscilloscope as shown in Figure. 2.0- 1.0- T0 ms Periodic signal from optical encoder The measurement data are given in the following table Motor speed n (rpm Period of rotation, T (sec) measured by Sensor Measured by Oscilloscope 200 312 400 500 600 700 800 900 1000 0.252 0.182 0.15 0.122 0.103 0.0895 0.078 0.0698 0.063 (a) Compute motor speed measured by oscilloscope (b) Evaluate the relative error % (c) Plot the relation between the ip and o/p data using the rectangular scales (d) Evaluate the linearity error and the zero drift (e) Determine the average sensitivity e the systematic error (uncertainty or accuracy) if the s measured
