Adder delay
A full adder circuit takes 20 ns to generate the carryout bit and 40 ns for the sum bit. When 4, 1 bit full adders are cascaded, the maximum rate of additions per second will be $\text{____} \times 10^6 $sec. Usual Solution given The ... calculate the total time taken to perform one round of four bit addition. Right? (Similar old question: https://gateoverflow.in/83500/digitals)

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) ?

Digital Logic
The 4 bit shift register is initialized to value 1000 for (Q3,Q2,Q1,Q0) . The D input is derived from the Q0,Q2,and Q3 through two XOR gates as shown in figure below . The Pattern 0001 will appear at pulse  ? D Q0 Q1 Q2 Q3 and logic gates are XNOR (order in image . I wrote it because in the image it is not clear) .

Find the number of integral solutions using generating function
Find the number of integral solutions of $\large 2x + y + z = 20$ with $x, y, z >= 0$ ? I tried finding coefficient of $x^{20}$ in $(1 + x^2 + x^3 + ...... + x^{10})(1+ x^2 + .......... + x^{20})^2$, but it gives wrong answer ?
