Question: ssignment no the rotating speed of a variable speed motor...

Question details

ssignment No 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 Tdisplayed by an oscilloscope as shown in Figure Periodic signal from optical encoder The measurement data are given in the following table Motor speed n (rpm) Period of rotation, T (sec) 200 400 .252 15 0.122 500 0895 0.078 0 0698 0.063 900 1000 (a) Compute motor speed measured by oscilloscope (b) Evaluate the relative emor % (c) Plot the relation between the i/p and op data using the rectangular scales. (d) Evaluate the linearity ermor and the zerodrift (e) Detemine the average sensitivity (f) Compute the systematic error (uncertainty or accuracy) if the speed measured by optical encoder repre sents the true value.
