revered members,
in the above link, for OR GATE, when either of the diodes are forward biased we get the output voltage as logic HIGH.
but for AND GATE, when when either of the diodes are forward biased or...
Hello Forum , please can someone help me to design the hardware of this table of logic (by the use of the logic gate) , the table is in the attachment.
Thanks in advance
I've been reading articles on logic gates and What I want to do before I get to school is familiarize myself with what individual components are used in making those individual gates on say a breadboard.I keep searching for it on the web but it just gives me the schematic symbols and not what...
Does anyone know if there is a relationship between the requirement in Quantum Computing that logic gates be reversible and the requirement in Quantum Mechanics that observables have to be self-adjoint?
Homework Statement
Using only AND and NAND gates, design a circuit in which 4 switches must all be turned on before a switch in another circuit turns off.
i think half the reason i don't understand may be the wording of his question, i know the tables but i am not sure how the logic gates...

Could someone please explain to me why these circuit arrangements act as AND/OR gates, can't find a decent explanation in any of my books
Hi! I'm new to this forum, just joined a couple of hours ago. I am an O-Level student and I am currently on revision leave. I would like some explanations on the basic working principle of logic gates and their uses in special circuits. The clearer the explanation the better and some links to...
[SOLVED] can u make "if A>=B then output=1 Else output=0" using these logic gates?
Homework Statement
this is not quite a homework problem. I am designing a device and I need to use A>=B comparator.
The challenge is I need to do this using only NAND, AND, NOR, OR and ExclusiveOR gates...
I need to understand how diode-resistor gates work. I've read a lot about what's supposed to happen based on inputs, but I need to see some numbers & analysis to understand what's going on. Where do you start in terms of trying to analyze the following AND gate...

I'm doing logic gates using their basic components MOSFETs. I have no idea how to understand which is the source and drain of the transistor from a symbol diagram when given both the n type and the p type. I also cannot understand what happens when the source is connected to ground. Can someone...
The very first part of the "electrical engineering and computer architecture for programmers" course I took glossed over a few things, and I have about 3 more questions, and thought I'd try online. They're in a fairly long html file with several diagrams, at...
Drawing Logic Gates!
hey guys,
im new to this posting thing on this site...if any of u belong to bossgtcentral.com, i am xcortman there lol... Anyway guys i am looking for a program that allows me to enter a boolean expression no matter how complicating it is and i want it to give me the Logic...
Hello all
Just refreshing for computer science midterm, and need to review logic gates. What exactly are logic gates? I know that they include AND OR XOR etc... but why is it really needed? Could you please provide some examples of their effiiciency in the real world?
Thanks a lot
What software can I use for drawing Logic gates? I am just too lazy to draw it by mouse and also drawing gates with different shape isn't elegant. So, I want a simple software that can draw Logic gates, And, OR, gates etc...
If I have an 8-bit ALU, how would I hook them up to do the layer thing (I don't know the name)? It's the thing that you start with 4 ALUs, then they go down to 2, then those go down to 1. Are all the inputs for each of the original 4 seperate, or do they share some inputs? How to two go down to...
Anyone know of a site that explains a 1 bit computer made from logic gates, or at least what all is needed for a one bit computer (all I know is an ALU)?
