Logical 1 means 'Yes', logical 0 means 'No'. The output F agrees with the majority of the inputs, except F votes No whenever C votes No. (a) Fill in the Truth Table below for this system. (b) Draw a realization for this system which uses at most 2 logic gates. EE 42, Midterm #2, Fall 1994) Problem #4. [20 points] 3 Solutions!

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
