The synchronous circuit shown in Fig,  where D denotes D-Flip Flop, produces a periodic binary output sequence. Assume that initially $x_1 = 1, x_2 = 1, x_3 = 0, x_4 = 0$ and that the initial output sequence is $1100101000$. Thereafter, this sequence repeats itself.

The function value $f(x_1,x_2,x_3,x_4)$ when $x_1 = 1, x_2=1,x_3=0,x_4=1$ is ?

Seq 1101 is not observed in output pattern.

Hence Function output can not be determined
