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 ?

Best answer
Seq 1101 is not observed in output pattern.

Hence Function output can not be determined
