A 7.5° stepper motor (four phase), controlled by a computer, is used to position a telescope through a gear train. The telescope must be positioned to within 0.01°. A front panel has toggle switches that are used to specify how far the telescope is to move (LSB = 0.01°). The total range of the telescope is 0-60°.
a. How many toggle switches would be required?
b. What gear ratio would you specify?
c. Draw a block diagram of the system, showing all parts of the system and specifying the gear ratio.
