Homework Statement
how can I implement 4 input xor gate like a+b+c+d (+ means xor gate symbol)
What gates do you have available? How many inputs can each have?abusayed said:how can I implement 4 input xor gate like a+b+c+d (+ means xor gate symbol)
A 4-Input XOR Gate is a logic gate that has four input signals and produces an output signal based on the exclusive OR (XOR) logic function, where the output is true if and only if an odd number of the input signals are true. This gate is commonly used in digital circuits for error detection and correction.
To implement a 4-Input XOR Gate, you will need four input signals (a, b, c, d) and one output signal. The output signal can be achieved by connecting the four input signals to four individual XOR gates and then connecting the outputs of those gates to a fifth XOR gate, which will produce the final output signal. Alternatively, you can use a specialized IC (integrated circuit) that contains multiple XOR gates, such as the 74LS86.
The truth table for a 4-Input XOR Gate is as follows:
a | b | c | d | Output |
---|---|---|---|---|
0 | 0 | 0 | 0 | 0 |
0 | 0 | 0 | 1 | 1 |
0 | 0 | 1 | 0 | 1 |
0 | 0 | 1 | 1 | 0 |
