Shown above is an optical encoder that can be used to measure position. The dark regions indicate opaque areas and the light sections are transparent regions. The circles represent LED/photodiode reading pairs. (As the disk rotates, readings under these fixed location components will vary.) Let a dark region produce binary ones (1) and the transparent areas generate binary zeros (0). (a) Produce a table that shows the codes as a function of the 16 positions shown on the encoder. (b) Describe a serious limitation with this arrangement. (Make sure that you provide a complete and detailed answer, not just a general response.) (c) What can you do to overcome this deficit?
can you expand a little bit on parts b and c ?
ok man got it thanks
