Problem in Master Slave

We have a problem in master-slave flip-flops. Consider a RS Master-Slave Flip-flop and following waveforms are the expected output of RS flip-flop While when we actually give the above inputs to RS master-slave flip-flop, we get the following outputs And we see that at the 4th and 5th edge we have the wrong transitions.  Why so? Before […]

Master slave Flip flop

We use 2 separate latches to construct a master-slave flip-flop. One latch acts as a Master and other acts as a Slave. Both are level triggered latches but one is latched on positive level and other on negative level.  Diagram of the RS master-slave flip-flop is as: First latch acts as a master and 2nd latch acts as […]
