can you guys give me more example of OR gate application aside from Doorbell and 2 floors stairway light and pls include the diagram. Thanks
That, or the OP has an assignment due soon and needs someone to answer one of the questions for him. Especially since he insists that we provide a diagram instead of just an idea of where an OR gate would be useful.Obviously the OP is just starting out and trying to learn something.
OMG, you don't get it.
Bill, pls check mailObviously the OP is just starting out and trying to learn something. The diagram linked in post #9 shows two switches on the left side.
These switches are shown in a position that supplies a ground to the input of the OR gate as well as supplying a current path to ground for the two LEDs that share the OR gate inputs.
The resistors shown in series with the LEDs are to limit the current so the LEDs are not destroyed.
They also provide what is called a PULL-UP function.
As drawn, the LED tied to the output of the OR gate will be ON when the switches are in the state shown since both inputs of the OR gate are at a logic 0,or ground, allowing current through the LED-resistor combination.
When either switch is changed from its current position, the resistor-LED combination associated with that particular switch will allow the voltage on the input of the OR gate to be PULLED UP to a logic 1 state.
The OR gate function will then allow the output of the OR gate to change to a logic 1 state and since the voltage on each end of the LED on the OR gate output will be the same, it will be turned off.
As for the use of an OR gate in digital logic, one is used any time more than one input needs to provide a single output without having any effect on other inputs. It provides isolation between inputs.
I hope the OP can follow this explanation. It is wise to remember that at one time this was all very strange for most of us.
wbahn, yah,my mistake ) 2 story is xorThat, or the OP has an assignment due soon and needs someone to answer one of the questions for him. Especially since he insists that we provide a diagram instead of just an idea of where an OR gate would be useful.
Interesting examples he gave, though. A doorbell? Only if there are multiple doors ringing the same bell, which is a bit unusual (how do you know which door to go open?) A 2-story stairway light using an OR gate? That's an example of an XOR gate.
Idea will dohe insists that we provide a diagram instead of just an idea of where an OR gate would be useful.
XOR gate.
No. I already gave you three. Perhaps after YOU put in some effort and sketch up a circuit for all three I will give you a couple more. But at some point YOU have start thinking for yourself.WBahn can you give more ideas pls
