2. Explain Rotate Right Operation of shift register with the help of Diagram. (Marks 3)
The serial output of the register is connected to the serial input of the register. By applying clock pulses data is shifted right. The data shifted out of the serial out pin at the right hand side is re-circulated back into the shift register input at the left hand side. Thus the data is rotated right within the register.
Also explain with diagram
Q2#Suppose a 2 bit up-counter, having states “A, B, C, D”. Write down  IF THEN ELSE statements to show how present states change to next state
Q3#Explain the difference between 1-to-4 Demultiplexer and 2-to-4 Binary Decoder?
Q4#

Draw the Truth-Table of NOR based S-R Latch
Q5#draw truth table of j-k flip flop with asynchronous input(  249)
Q#6 3 bit synchronous counter table was given and we have to complete it
One question was totally conceptual based.
Rest of questions iforget for that sorry
Mcqa were mostly from moaz past pprs file
This was my ppr
And wish u  all  best of luck
Stay 😊

2ND PAPER

Cs302 today’s paper 8 am
40 mcqs 10 subjectives
Mcqs were mostly from past papers almost 30 from past
1
Applications of ROM atleast two
2
If address lines are 12 then how much memory locations will be access justify
3
Which register save address of top of stack if 2 and 3 are added to stack then what is incrementing/ decrementing value of that particular top stack register,justify why increment or decrement value of that register
4
Sum of product was given for A,B,C we have to made k.map of it and also map corresponding cells
5
One Flip flop was given we have to name it
6
3 bit a synchronous up counter was given we have to connect 3rd flip flop with second
7
Sum term was given we have to make expression from it
8
Moore machine table was given we have to made state diagram from it
9
4-bit Parallel In/Serial Out Shift register was given we have to connect some of states
10
Timing diagram of any flip flop was given we have to make output Q of it
