a) A single turn (360 ) optical encoder is to replace a

a) A single turn (360 ) optical encoder is to replace a 10-turn potentiometer (3000 of movement full scale) with a total of 5000 turns of wire. Assume that the proper gearing is provided to assure 360 revolution of the encoder from one end of the linear displacement to the other. Calculate the pulse per revolution needed. It is necessary to measure a linear displacement of 10 cm with a resolution of at least 0.02 mm. Explain how this can be done using a 10-turn potentiometer (3000 of movement full scale) with a total of 5000 turns of wire.
