This is very informative intructable post

Most of us don't know the secret behind the simple NOT GATE

NOT GATE is nothing but a single transistor

You can make easily in 2 minutes also you can verify the out put .....

Check out the complete video tutorial.....

<p>While this circuit does invert the signal in your simulation, it is not actually a NOT gate. A correct NOT gate would be actively driven. For a 5V TTL circuit: if the input is at least 2V, the output is pulled high (5V); but if the input goes below 0.8V, the output is pulled low (0V).</p><p><a href="http://www.allaboutcircuits.com/textbook/digital/chpt-3/not-gate/" rel="nofollow">http://www.allaboutcircuits.com/textbook/digital/c...</a></p><p>https://en.wikipedia.org/wiki/Inverter_(logic_gate...</p>
yes you right <br><br>low level is considered here 0.7 - 0.8 volt <br>
Not exactly. For TTL, you are right. However, for DTL, you are incorrect--passive pull up is used.
<p>&quot;This is very informative intructable post&quot; ....</p><p>Well... I think NOT. Just a video without any ohters materials( schema/parts/tools/values) if you want to win videos view this isn't your site. Please, post images with more info and some text. THIS is the idea of Instructbles, not a site to win YT views</p>
OK bro <br>In all my upcoming instructables I will share each and every things required to make a featured and good instructables<br><br>thanks for your advice
