Question 6a and b are: Draw the logic diagram for the following Boolean expression. Then simplify the Boolean expression in (a) using a karnaugh map. The picture goes into more details about the assignment.

Sometimes "bubbles" are used to indicate inverters on the input lines to a gate. What are the equivalent gates for those shown in the figure below? Hint - use DeMorgan's Law. A B C=A+B (a) D F=DE E (b)

---CIRCUITS TO BOOLEAN FORMULAS--- Write a Boolean formula for the following circuit:

Grey converters are often used in industrial circuits where the normal sequence of binary numbers may produce ambiguity during transition. This is elliminated with the Grey code, as only one bit changes, during a normal transition of sequential numbers.   Show the logic required to convert a 10-bit binary number to Gray code and use that logic to convert the following to Gray code: a)      1010101010   b)      1111100000  c)      0000001110  d)  1111111111

please help just answer as much as you can, no need to complete all. thank you
