Natwerk Designs

Can someone please help me with my Digital design homework thanks..?

1.Using Karnaugh maps, find a minimal sum-of-products expression for each of the following logic functions: (1)F=∑x,y,z(1,3,5,6,7) (2)F=∑w,x,y,z(1,4,5,6,7,9,14,15) (3)F=∑w,x,y,z(0,1,6,7,8,9,14,15) (4)F=∑A,B,C,D(4,5,6,11,13 ,14,15) 2.Using Karnaugh maps, find a minimal sum-of-products expression for each of the following logic functions: (1)F=∑w,x,y,z(0,1,2,8,11)+d(3,9,15) (2)F=∑A,B,C,D(1,5,12,13,14,15) +d(7,9) 3.Using red, yellow and green indicator lights to indicate the working state of 3 devices in this way: green light indicates that all of the device are OK, red light means that one of the device does not work, yellow light means that two of them do not work. If both red and yellow lights are on, all of them do not work. Please design the control circuit.

1. Good luck with that. K-maps are easy, but even I couldn't understand what you're trying to say. You're best bet would be to go here and study up or get help from your professor: http://en.wikipedia.org/wiki/Karnaugh_map Hope this helped.
