Digital Logical(Xor and Xnor Gates)
1. Xor and xnor are same in case number of inputs of odd? 2.If above is yes,then why do we say these ae complement? 3.Are these associative and commutative for more than 2 i/p? 4.How do we correctly define them for more than 2 i/p?Is it just that exor checks odd no. of 1's and xnor checks even number of 1'a? 5.Why exnor is called as even function?

Simple Doubt in digital
Consider a simple OR gate with 2 inputs A and B, a ouput O which is taken back and reconnected to B as feedback. Now, A=0 and B=0 so O=0. If we give A=1 for like 1 sec , O=1 and now if we turn off the power from the circuit , 1.) will we get a infinite ... it and and O=1 (Assume a case when A=1,B=0 so O=1 , Now i quickly set A=0 , will this not automatically make B=1) ?

Both XOR gates and all wires have zero delays. Assume that all gate inputs, outputs, and wires are stable ... change of logic levels) occur(s) at $B$ during the interval from $0$ to $10$ ns? $1$ $2$ $3$ $4$

Express the function $f(x,y,z) = xy' + yz'$ with only one complement operation and one or more AND/OR operations. Draw the logic circuit implementing the expression obtained, using a single NOT gate and one or more AND/OR gates. Transform the ... circuit (without expressing its switching function) into an equivalent logic circuit that employs only $6$ NAND gates each with $2$inputs.
