[Guide] Design a NOT gate by using Diode and Resistance

[julia]

I’m having a home work that required is design a NOT gate by using Diode and Resistance, who know please draw it for me, I need guide and reference. Thank you very much.

Perhaps you should look at wikipedia...

Julia, what is a NOT gate? Are you sure you are limited to only resistors and diodes?

design a NOT gate by using Diode and Resistance

imho that is impossible using diodes and resistors only. You will need at least one additional active element, e.g. a transistor. For that case you'll find plenty of descriptions on the internet.

oh it required make by my teacher, he give us that question, I have research that I still haven't answer, who help me ?

A Diode can only pass a Signal. Either low voltage, if the cathode is connected to the input, or high voltage, if the anode is connected to the input. In any case, the polarity of the Output is the same as for the input. Look up "Diode Transistor logic" or DTL in e.g.the Wikipedia. You will find that an additional Transistor is required to generate the inverse signal

Read the very first paragraph of the wikipedia entry for resistor/diode logic.

Clearly you're not much interested in doing your own research.

However there is one way of doing it that requires no components at all (but it's cheating and typically impractical)
