Question

Convert the following decimal numb er (450)m into octal number system ? Convert the following binary number 1101100000110 into itsoctalequivalent ? Describe the function table of AND, OR, and NAND ?

Answer 1

450 =(702)₈

1101100000110=(15406)₈

Refer to the images for the Truth tables for the AND , OR , NAND gates.

The output of OR gate is High when either of the inputs is 1.It is 0 only when both the outputs are 0.

The output of AND gate is 1 only when both the inputs are 1.If either of the input is 0 output is 0.

The NAND gate is Not AND gate So we have to just reverse the output of AND Gate.Replace 0's to 1's and vice-versa.
