Flip Flops

-

 Definition:- 

Flip flop is a one bit memory cell that can store one bit of data. A group of flip-flops are called register.

For example:- If we want to store data 1111 then we need four flip Flops.

Flip-flop is basically used in digital electronics. It is used to store digital numbers.

Flip-flop is a sequencial circuit ( sequencial circuit are those whic has memory, out put of sequencial logic circuits are depends upon present input and past output.

Latch is also one bit memory cell but basic difference between latch and flip flop is latch is level trigger and flop is edge trigger ( latch works on low level or High level of clock pulse and flip flop works positive or negative edge of clock pulse.


                                Clock pulses


Types of Flip-flops

There basically four types of Flip-flops

1- SR (set-reset) Flip-flops

2-D(delay) Flip-flops

3- JK (jack-kilby ) Flip-flops 

4- T (toggle) Flip-flops

Gates(digital electronics) Gates are basic building block of digital electronics.there are 7 gates used in digital electronics. They are as follows- 1-AND gate 2-OR gate 3-NOT gate 4-NAND gate 5-NOR gate 6-EX-OR gate 7-EX-NOR gate Where NAND and NOR called 'Universal Gate'.Because with the help of these two gates we can make all other gates. Now we will explain each gates with their truth table.here truth table are used for verify it's operation. 1-AND gate Symbol and truth table of AND gate 2-OR gate 3-NOT gate 4-NAND gate 5-NOR gate 6-EX-OR gate Where  (A ⊕ B)= A B  +  A B 7-EX-NOR gate
