### NOR gate | Universal Gate | How to construct different gates using NOR gate? | DE.15

we will talk about the nor gate while constructing the six case using the nor gate the trick is to remember which keep to construct first and last we will start with an odd gate let's recap the truth table for nor gate nor gate produces an inverted output for these two input combination they're both the inputs are at the same logic level so we will short the two inverse of nor gate then the input is at logic 0 the output is 1 and vice versa this is not gate constructed using a single nor gate the second case we would construct is a nor gate from nor gate now this is simple if you complement the output of northeast we get a nor gate but we connect a single input nor gate we have done this using to give nor detachable in expression A or B bar where a and B are the two inputs however if the two inputs a be afforded by a knotty peek at a bar and B bar these two outputs will be connected to a nor gate the boolean expression as a bar or B bar and the whole term inverted if we apply dimmable theorem to s the output is a and B which is the logical expression for a NAND gate we have used three nor G's for this if you compliment the output of angles we get Anandi's such language is obtained using four nor gives the fifth Gibbs will construct is an XOR gate to Kirika lipsticks nor expressions this ax nor D and it can be expanded this way that is a and B or e bar and Dheeraj let's take the angie's constructivism vanadis and connect one more nor gate ahead pause the video and try to solve this so it gives the logical expression of an X nor gate the last cave is an XOR gate it is obtained by inverting the output of an X nor gate that is by connecting one more nor gate thank you for staying till the end of the video and for all your lives to connect to us and share the last stay calm and keep learning peace out

It's such a helpful animation video

best video ..

keep uploading ..

love from nepal..

That was helpful. Thank you
