                        CLOCKED F

In a large digital system with many flip
          are required to be synchronized
          the operations of the system ma

                       R

    c
(clock)

     S

Clock pulse allows the flip flop to chan
when there is a clock pulse appearing

We call above flip flop a Clocked RS L
