hey guys i need logic diagram for these question on karnaugh map. i would be happy if you can draw the logic diagram on "Paint" or.... and upload it on imageshack for me....

1)A 4-bit binary number is represented by A,B,C and D with A being the MSB. design a logic circuit that will produce a high output whenever the binary number is less than 0100 and equal or greater than 1010.

2)A 4-bit binary number is represent as D,C,B,A where D,C,B,A represent the individual bits with A equal to the LSB. the logic circuit with this 4 bit binary number will produce a HIGH ouput whenever the binary is greater than 0011 and less than 1110.

3)A 4-bit binary number is represented by A,B,C and D with A being the MSB. X denotes the "dont care" condition.
0000 = 1
0001 = 1
0010 = X
0100 =X
0110 = 1
1000 = 1
1001 =1
1110 = X
1111 = 1

Thanks for anyone whom take the time and draw out the logic diagram of this karnaugh map questions for me!!!

Please specify exactly what you need help on and show your progress thus far.

The karnaugh map is used to design circuits using the smallest number of components. Therefore, a thorough understanding of it's use is essential. As a professional engineer, you will be expected to research and resolve design issues.
