Hi i am working on my digital electronics project 4-bit even odd parity generator and checker this is my circuit.how do i implement this on breadboard and what am i missing here except the vcc and where to place the led's to show even odd. Thanks
You wanna use IC 7486 quad xor gate.It has 4 xor gate in it.the pin diagram is like the first image.
There's are good examples at homofaciens.de for each of the standard logic functions. XOR is one of the trickier ones to implement but it can be done like this.
How it works
A and B low: The output is low since there is no power through D1 or D3 to drive the output high.
A high - B low: Output will be high because 'A' will feed the OUT terminal through D1. D4 will pull Q1's gate low turning off Q1 preventing it from pulling OUT low.
A low - B high: Output also high by same logic as previous example.
A high - B high: Output low. Even though the left side of R3 is high the right side will be pulled low by Q1 because the gate is pulled high by R1.
You could make this into a four or five (or any number) input gate by adding more diode pairs.
Calculating the component values is left to the OP.
