Its simple exclusive or gate b/e x, y (any thing a,b etc..) combined with another exclusive or gate of z. i was trying to past a pic...but this sheet does not allow.....
x----`````
! ! `----
y----```` -
----- `````
----- !! `------------
z--------------- `````
suppose if we apply 010 to xyz, then XOR of xy (01) is 1 then XOR of previsou 1 (xy) and z is again 1 which is output,....so to make even 1's we 'll add 1....
another example lets take input 101...then XOR of xy (10) is 1 and XOR with z (1 with Z) that is 1 and 1 is zero which means that input 1's are already even so no additional 1 is needed.

How do you convert a 4 input NOR gate into multiple 2 input NOR gate?
you will need 2 two input AND gates to do this. connect the output of the first to one input of the second. you now have a three input AND gate. just remember when calculating timing that 2 inputs of the 3 have twice the gate delay of the remaining input, thus the output will have skew and possibly glitches. if timing is critical or glitching can't be tolerated it may be best to use an actual three input AND instead of kludging one.
How a latch works?
Computer Architectures - Digital Circuits - Latches and flip-flopsIn the same way that gates are the building blocks of combinatorial circuits, latches and flip-flops are the building blocks of sequential circuits.While gates had to be built directly from transistors, latches can be built from gates, and flip-flops can be built from latches. This fact will make it somewhat easier to understand latches and flip-flops.Both latches and flip-flops are circuit elements whose output depends not only on the current inputs, but also on previous inputs and outputs. The difference between a latch and a flip-flop is that a latch does not have a clock signal, whereas a flip-flop always does.LatchesHow can we make a circuit out of gates that is not combinatorial? The answer is feed-back, which means that we create loops in the circuit diagrams so that output values depend, indirectly, on themselves. If such feed-back is positive then the circuit tends to have stable states, and if it is negative the circuit will tend to oscillate.A latch has positive feedback. Here is an example of a simple latch:
Why is Bill Gates name gates?
His last name is Gates, because Gates is his family's name. His last name Gates comes from his ancestors.
What are the two main categories of logic circuits?
The following are all common digital electronic logic gate types: AND OR NAND NOR XOR NOT There 'truth tables' and therefore their corresponding functions can be found on wikipedia under articles entitled with their respective names. NAND is a very common gate in commercial digital electronics as all other gates can be imitated by connected the correct number of NAND gates in the correct way. These can then be placed on one IC (Integrated Circuit) chip which reduces cost massively.

How do you simplify this circuit?
To simplify a circuit you must first find a Boolean expression for the circuit and then apply Boolean algebra to take it down to the simplest form, to implement the fewest gates.
Why some of the logic circuit required another gates to construct the operation?
Because not all the logic gate have what the circuit needs to complete the operation

it should produce a trigger pulse at a time.
