AI Thread Summary
To build an AND gate using a 2X1 multiplexer, one input can be fixed while the other serves as the select line, allowing the output to reflect the AND operation. For a NOT gate, one input must be fixed to either 0 or 1, with the other input connected to the variable input, effectively inverting the signal. The discussion emphasizes understanding the role of fixed inputs in the multiplexer configuration. Clarification on the number of inputs required for each gate type is also provided. This approach guides users in constructing logic gates using multiplexers effectively.

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!
