An absolute optical encoder has 10 rings and 10 led sensors, in turn, provide 10-bit outputs. The bit pattern output reads 1100011100. a) Sketch the encoder rings and led sensors circuit then discuss its working principle and applications in robotic systems. b) Calculate the encoder resolution and the absolute angular position of the shaft. c) What the equivalent gray code for the same angular position of the shaft?
