Master-Slave Flip-Flop
shape of the clock waveform, since only the voltage levels at the clock inputs
control the transfer of information from data input (D) to output.
affects only the “Master” portion of the flip-flop. The data present in the “Master”
is transferred to the “Slave” when clock inputs (C1 “OR” C2) are taken from a
low to a high level. In other words, the output state of the flip-flop changes on the
positive transition of the clock pulse.
