Please see the attached file.
First we need to recall the truth table f the SRFF:
S R Qn+1
0 0 Qn
0 1 0
1 0 1
1 1 N/A
Note that Qn+1 follows the input S except when S=R. When S=R=0 the ouput is unchanged, while if S=R=1 the input settles in an undetermined state.
Now we write the functions for S and R:
It is obvious that when Φ=0, both S and R are kept at zero, hence there is ...
