(a) A=A(H)=AL)( =A(H)=AL)(
(b) A=A(H)=A(H)=A(H)=AL)(
(2) To fully specify a circuit, you need to provide a Signal List (SL) in addition to function. If
the SL is not provided, then it will be assumed to be positive logic.
(a) PLC F=A.B + C.D; SL: F ABC,,,, D
(b) DPI F=A.B + C.D; SL : F(H), A(H), B(L), C(L), D(H)
