A digital thermometer produces a continuously varying voltage signal between 0V and 5V, where 0V represents 0 degrees and 5V represents 100 degrees. This signal is digitized using an Analog-to-Digital converter that produces an 8-bit binary number proportional to temperature, where 00000000 represents 0 degrees and 11111111 represents 100 degrees (so each binary number represents a multiple of 100/256 degrees). Use switches to emulate the thermometer output and an LED to indicate when the temperature is within the desired range. Required:
Write a test bench to simulate your design before implementing it on your board.

Ashielded metal arc-welding operation is accomplished in a work cell by a fitter and a welder. the fitter takes 5.5 min to load components into the welding fixture at the beginning of the work cycle, and 1.5 min to unload the completed weldment at the end of the cycle. the total ength of the weld seams 1200 mm, and the travel speed used by the welder averages 300 mm/min. every 600 mm of seam length, the welding stick must be changed, which takes 0.8 min. while the fitter is working, the welder is idle (resting): and while the welder is working the fitter is idle. (a) determine the average arc-on time as a fraction of the work cycle time. (b) how much improvement in arc-on time would result if the welder used flux-cored arc welding (manually operated), given that the spool of weld wire must be changed every 10 weldments, and it takes the welder 5.0 min to accomplish the change? (c) what are the production rates for these two cases (weldments completed per hour)? attach your work and solutions.
