What are Flip-Flops?
The flip-flops are basically the circuits that maintain a certain state unless and until directed by the input for changing that state. We can construct a basic flip-flop using four-NOR and four-NAND gates.
Types of Flip-Flops
The flip-flops are of the following types:
1. S-R Flip Flop
2. J-K Flip Flop
3. T Flip Flop
4. D Flip Flop
Below, you can find the logic diagrams along with the truth tables of all the various types of flip-flops:
Converting Flip-Flops
Here we will discuss the steps that one must use to convert one given flip-flop to another one. Let us assume that we have the required flip-flops that are to be constructed using the sub-flip-flops:
1. Drawing of the truth of the required flip-flop.
2. Writing of the corresponding outputs of those sub-flip-flops that are to be used from the given excitation table.
3. Drawing of the K-Maps using the required inputs of the flip-flops and then obtaining the excitation functions for the inputs of the sub-flip-flops.
4. Construction of the logic diagram in accordance with the functions that we have obtained.
