Use truth table of basic NOR gate to establish that it can functions as basic Comparator

Solution

Sure, let's establish that a NOR gate can function as a basic comparator using its truth table.

A NOR gate is a digital logic gate that behaves according to the truth table below:

A B Output
0 0 1
0 1 0
1 0 0
1 1 0

A comparator is a device that compares two binary or digital inputs and outputs a binary signal that indicates the result.

In the case of a basic comparator, we are interested in whether the two inputs are equal. If they are equal, the output is 1 (or true), and if they are not equal, the output is 0 (or false).

Looking at the truth table of the NOR gate, we can see that the output is 1 only when both inputs are 0. In other words, the NOR gate outputs 1 when both inputs are equal (both are 0), and 0 when the inputs are not equal (one or both are 1).

Therefore, we can conclude that a NOR gate can function as a basic comparator, specifically for the case when both inputs are 0.
