Question #199441

A PN flip-flop has four operations: clear to 0, no change, complement, and set to 1, when

inputs P and N are 00, 01, 10, and 11, respectively.

(a) Tabulate the characteristic table.

(b) Derive the characteristic equation.

(c) Tabulate the excitation table.

(d) Show how the PN flip-flop can be converted

to a D flip-flop.

Expert's answer

(a) Tabulate the characteristic table.

(b) Derive the characteristic equation.

"Q (t+1)= P\\bar{Q}+NQ"

(c) Tabulate the excitation table.

(d) Show how the PN flip-flop can be converted

By connecting P and N together, we get: "Q (t+1)= D\\bar{Q}+DQ=D"
