Question

Consider a clocked sequential circuit as shown in the figure below. Assuming initial state to be Q₁ Q₀ = 00
For an input sequence X = 1010, the respective output sequence will be _______.

Comments

1(LSB)110(MSB).....???

$1010$ is the answer.

Answer 1

It is coming 1010(from X=0(LSB) to 1(MSB))

Can you take a picture of your solution and then attach it in your comment.

I am getting same answer but in key 1001 is given.

Answer 2

Output is Y = (MSB) 0011 (LSB)

Comments

Instead of Q0(New)XORQ1(New) only Q0(New) will come in the second last line.

Answer 3

I am also getting 1010 as the answer

Answer 4

Answer is 1011

D1	D0	Q1	Q0	Output Y
Q1 XOR X	Q0 XOR Q1	0	0	X'Q1'+Q0'
when x=0, 0 xor 0 = 0	0 xor 0 = 0	0	0	1
when x=1, 0 xor 1 = 1	0 xor 0 = 0	1	0	0
when x=0, 1 xor 0 = 1	0 xor 1 = 1	1	1	1
when x=1, 1 xor 1 = 0	1 xor 1 = 0	0	0	1

Comments

no answer must be (- - 10)i.e. end with 10

I dont think i did anything wrong in the solution.
