EE 4770 Homework 3 Due: 13 March 1998 In the following two problems a system to measure the angle, distance, and speed of a rotating disk will be designed. The disk can rotate clockwise and counterclockwise, and can change direction at any time. The system need not determine angle and distance until the disk has made one full rotation, but then must update them as frequently as possible. The disk has space for three rings of marks; the transducers, conditioning circuits, and interfaces for the mark readers are provided (they are not part of the solution). The first problem is to determine the placement of the marks, the second problem is to write the interface routine (actually, an interrupt handler). Problem 1: Show how to place marks on the three rings to achieve maximum precision, remem- bering that rotation direction can change; each ring can have up to 1024 marks. Clearly show how the marks are positioned. For convenience, the mark rings can be shown as linear tracks. Hint: Straightforward adoption of a coded displacement transducer presented in class would yield a
