A not gate is a logical gate which inverts a digital signal. If the input to a not gate is 1, then the output will be 0. If the input is 0, then the output will be 1.
Our Brain
and gates or gates nor gates nand gates are the electronics logic gates.
There is no specific syllabus. It might be similar to GATE syllabus. I suspect questions to come from old GATE papers
You can construct a NAND gate using relays. If the contacts are in series, it is an AND gate. If the contacts are in parallel, it is an OR gate. Depending on which contact you use, it is a NOT gate. Simply pick the right combination of contacts and the meaning of the signal, and you can consider it to be a NAND gate.
i want to ask that how can i prepare for gate examination. and my subject for gate is electronics. and i want to prepare for gate at home. so provide me a good material of books and notes which can help me for that. and me want to be a scientist so how can i prepare for it also.

You can find the information of gate question paper on the site of IISc or IITkgp and you can download the question paper of gate (previous) at gurukulinfo.com and also on other site by searching on any search engine with appropriate keyword.
During the Old Days As Electricity evolved trough the world, Electronics came up. (You) Tube or Conduit is what they called to this electronics parts they place in Television or Radio. This are Capacitor, Inductor, Resistance, etc made in a big material made of Glass Tube or Glass Conduit they called. This Capacitor. Inductance, Resistance are now made Digital Electronics which place inside our Flat Television, Small Radio, Modern Camera, Computer (Desktop or Laptop), etc. Now i will name some of few how they call this now. X gate. Y gate, Or gate, Nor gate, Grid place in a small digital elctronic which we used today.

study all your course again and read rk kanodia books. this is bes method for prep.
Graduate Aptitude Test in Engineering (GATE) is an exam for admission to Masters level programs in most engineering institutes in India. For GATE ECE the best book is gate EC by RK Kanodia. Dont go for GK's publsihers book. This will be wastage of time and money because it contain lot of errors and lot of questions are copied from RK Kanodia book directly.
If your branch is Electrical/Electronics then in my opinion Primus IES/GATE coaching classes are the best ies coaching institute in Delhi that I have seen. You get high personalised attention and there last two year results have been good too. their site is: www.primusies.in
