SUMMARY

This discussion focuses on constructing an AND gate and a NOT gate using a 2X1 multiplexer. A 2X1 multiplexer has two inputs, one select line, and one output. To create an AND gate, both inputs should be connected to the multiplexer without fixing any input values. For the NOT gate, one input must be fixed while the other input is connected to the multiplexer. These configurations allow for the desired logical operations to be achieved effectively.

PREREQUISITES
  • Understanding of digital logic gates
  • Familiarity with multiplexers, specifically 2X1 multiplexers
  • Basic knowledge of Boolean algebra
  • Experience with circuit design concepts
NEXT STEPS
  • Research the operation of 2X1 multiplexers in digital circuits
  • Learn about constructing other logic gates using multiplexers
  • Explore Boolean algebra simplifications for circuit design
  • Study practical applications of multiplexers in digital systems
USEFUL FOR

Students in electronics or computer engineering, hobbyists building digital circuits, and educators teaching digital logic design concepts.

Homework Statement


Hi,
How to build a AND gate using a 2X1(2 inputs, 1 select,1 output) multiplexer?
The same for a NOT gate?
I am stuck on it!
thank you


Homework Equations





The Attempt at a Solution


Sorry I tried but I am confuse about what are consired as input if we decide to fix one input.

If you decide to fix one of the inputs, it'll still be considered an input, just an input that always has the same value.

HINT1: How many inputs has an AND gate? You shouldn't need to fix any inputs on your MUX (at least, not to 0 or 1)
HINT2: How many inputs has a NOT gate? You will need to fix MUX inputs.
 
Thank you
I will work on it!
