output is feedback in input
To produce a 3-input OR gate when only 2-input OR gates are available: Use 3 OR gates Inputs to Gate A are input 1 and input 2 Input to Gate B is input 3 (if 2 inputs are necessary, include input 3 and FALSE) Inputs to Gate C are outputs from Gate 1 and Gate 2 === If input 1 OR 2 is TRUE, output of Gate A will be TRUE. If input 3 is TRUE, output of Gate B will be TRUE. If output of Gate A OR Gate B is TRUE, output from Gate C will be TRUE. That is if one ore more of Inputs 1, 2 or 3 is TRUE, the result will be TRUE. Otherwise, output of Gate C will be FALSE.

For two input AND gate it is 7408for three input AND gate it is 7411
connect the output of two input or gate with the two input or gate1.one input of or gate no.1 is output of or gate and another input is taken and hence final output of or gate no1 is formed three input or gate. i.e let o/p of or gate is A+B which is one i/p of gate no1. and let another i/p is C. and final i/p is Y=(A+B)+C=A+B+C
this shows you everything you need about them Pin Number Description 1 A Input Gate 1 2 B Input Gate 1 3 Y Output Gate 1 4 A Input Gate 2 5 B Input Gate 2 6 Y Output Gate 2 7 Ground 8 Y Output Gate 3 9 B Input Gate 3 10 A Input Gate 3 11 Y Output Gate 4 12 B Input Gate 4 13 A Input Gate 4 14 Positive Supply
All inputs hae to be low i.e 0.
To get a not gate (or inverter) from nor gate, tie the two input together. If fan-in is a concern, tie one input to logic false and drive the other input.
You would connect the output of the first AND gate to one input of the second AND gate. You are left with 2 inputs on the first AND gate and 1 input on the second AND gate. The final output is from the second AND gate.
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.
Truth table for a 3 input NAND gate?
A "Not" gate is also called a "hex inverter". It's a binary logic gate that inverts the input. If the input is "1", the output will be "0".
A four input and gate is a logic gate with four inputs. The output is true only when all four inputs are true.
you can take 2 input or gate first 2inputs and output of that gate should be given as the input for next OR gate with 3rd input Above solution will not work if all 3 inputs are True. I believe the question requires a configuration of XOR gates that will produce a True result if EXACTLY one out of three inputs is True. Specifically, if Inputs A and B are both True, the first XOR Gate output will be False. If Input C is also True, the second XOR Gate output will be True, yielding an overall TRUE result. This is not the desired result. I don't know the correct answer, but I'm pretty sure the first answer is not complete. Truth table for 3 input XOR gate INPUTS OUTPUTS ABC X 000 0 001 1 010 1 011 0 100 1 101 0 110 0 111 1 From the table we can use 2 XOR gates to get 3 inputs XOR with the same result. 1st XOR Gate AB X 00 0 00 0 01 1 01 1 10 1 10 1 11 0 11 0 2nd XOR Gate XC Y 00 0 01 1 10 1 11 0 10 1 11 0 00 0 01 1 I was also confuse for when 3 inputs are 111, but I'm now sure from few references saying that 111 input will produce an output of 1.
Technically, an OR gate could function with only one input, in which case it would perform the same as if it was not present; when its only input goes high, it would go high, and when the input goes low, it would go low. As a practical matter, the only useful purpose of a single input OR gate would be to have it act as a simple diode, which would be more efficient to simply have a diode in its place.
Use 2 AND gates to input the 4 i/p signals and then use the outputs of these 2 AND gates in the 3rd AND gate to get the desired output.
OR gate gives the output 1 whenever one of its input is 1.
Gate current is denote by Ig
The OR gate
tie one input of the XOR gate high.
No. In the general case, a buffer amplifier is an analog device, but an AND or an OR gate is a digital device. Even in the specific case of a digital buffer amplifier, its still not the same because the digital buffer amplifier has more power available in its output circuit, giving it a higher fanout than just an ordinary AND or OR gate.
