Logic operators:
Logical operators are used perform the logical operations between two variables. Logical operator are used to connect two relational expressions into one or used to reverse the logic of the expression.
- The logic operators are AND “&&”, OR “||”, NOT “!”:
- Logical operator AND “&&” is used to determine whether the range is inside the specified numeric range.
- Logical operator OR “||” is used to determine whether the range is outside the specified numeric range.
- The logical operator NOT “!” is used to reverse the operands, if the returned value is true it is converted to false and vice versa.
AND “&&” operator:
It is used in connecting two conditional expressions, which can be represented as single expression. It works when both conditions are evaluated as “true”. When both conditions are evaluated to “true”, then the complete expression is evaluated as “true”.
Truth table of AND “&&” operator:
Expression 1 | Expression 2 | Value of complete expression |
True(1) | True(1) | True(1) |
True(1) | False(0) | False(0) |
False(0) | True(1) | False(0) |
False(0) | False(0) | False(0) |
OR “||”operator:
It is used in connecting two conditional expressions, which can be represented as single expression. It works when one conditions is evaluated to “true”. When one condition is evaluated to “true”, then the complete expression is evaluated as “true”.
Truth table of “||” operator:
Expression 1 | Expression 2 | Value of complete expression |
True(1) | True(1) | True(1) |
True(1) | False(0) | True(1) |
False(0) | True(1) | True(1) |
False(0) | False(0) | False(0) |
NOT “!” operator:
The logical operator “!” is used to reverse the operands truth or false hood. When the given expression is “true” it will negate the given expression to “false” or vice versa.
Truth table of “!” operator:
Given expression | Output expression |
!True(1) | False(0) |
!False(0) | True(1) |

This ALU will implement a bitwise left rotation. Forthis lab assignment you are not allowed to use Digital's Arithmetic components.IF YOU ARE FOUND USING THEM, YOU WILL RECEIVE A ZERO FOR LAB2!The ALU you will be implementing consists of two 4-bit inputs (named inA and inB) and one 4-bit output (named out). Your ALU must rotate the bits in inA by the amount given by inB (i.e. 0-15).Part-1: User InterfaceYou are provided an interface file lab2_part1.dig; start Part-1 from this file.NOTE: You are not permitted to edit the content inside the dotted lines rectangle. Part-1: ExampleIn the figure above, the input values that we have selected to test are inA = {inA_3, inA_2, inA_1, inA_0} = {0, 1, 0,0} and inB = {inB_3, inB_2, inB_1, inB_0} = {0, 0, 1, 0}. Therefore, we must rotate the bus 0100 bitwise left by00102, or 2 in base 10, to get {0, 0, 0, 1}. Please note that a rotation left is…arrow_forward
