here:

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!!!
