5. One of the command line Interface Operating system: UNIX (R)
(iv) Conversion and Summation
We need to convert (hexadecimal) and (binary) to decimal and then add them.
Hexadecimal to Decimal:
Binary to Decimal:
Sum:
(v) Boolean Equation
We need to write the boolean equation for the given logic circuit. The circuit consists of OR gates and an AND gate and NOT gate (inverter).
Let's break down the circuit step by step:
The first OR gate takes inputs and . Its output is .
The second OR gate takes input . The output of is inverted, resulting in . The OR gate takes inputs and . Its output is .
The output is then equal to .
