1. Design a 6 bit DACthat accepts digital voltages of 0 V (meaning binary zero) and 2 V(meaning binary one). The output must vary from +0 V (for code000000) to +5 V (for code 111111).

2. You discover that theengineer providing you the digital inputs did a terrible job with tolerances and that the voltage levels of 0V and 1V can drift up to+-0.15V. Design a front-end for the results of part 1 to deal with this problem.

3. The customer forgot to tellyou that they need the bias (0V at 00000) to be user-adjustablebetween 0V and 2V and that the range (5V between 000000 and 111111)must be user adjustable between 3V and 7V. Design a back-end(additional circuit) that connects to the results of part 1. Useone potentiometer for each function. Consider how to make thetwo functions independent - the range does not change whenthe bias is adjusted, for example.
Note - the final circuit is rather complex and will have many possible implementations. If you do sloppy work, you will getthe design wrong and the grader will also not be able to understandwhat you did (and that is valid cause for taking offpoints). AT LEAST use a ruler for circuit layout - asimple drawing program might be an even betteridea. Include all the required informationto implement your design including the power-supply voltages forthe op-amps.
