Question: Q$2)$ The following Figure shows a circuit with $4$ inputs $($a$,$b$,$c$,$d$),$ one output $($F$)$ and $2$ internal nodes $($x$,$y$).$ An LFSR will be used to generate test vectors and an SISR will be used for result analysis. The initial value for the LFSR and SISR are $"1001"$ as shown in the Figure $.$ Answer the following questionsa.
