Hello everyone, I have an exam in a few days and need help with a question on one of the past exam papers. An optical position encoder used on a robot axis has a 10:1 gear ratio, an optical disc with 72 slits, and a 12 bit binary counter. Determine: (i) The resolution of the encoder i.e. the minimum angular movement of the measured shaft that can be detected? (ii) The maximum allowable shaft motion to ensure that the counter never over-ranges? (iii) The amount of shaft movement represented by a binary output of 0101 1111 0010? For (i), the encoder has a 12 bit binary count, so the resolution will be: 360/2^12 = 0.088° Im not sure what to do for (ii) and for (iii), I understand that the binary output corresponds to the numbers 5 15 2 but what do I do with them, if i even need them?
