Applications of Flip-Flops:
Some of the common uses of the Flip-Flops are as follows:
1) Bounce elimination switch
2) Latch
3) Registers
4) Counters
5) Memory, etc.
Some examples of uses of Flip-Flops are given below:
A) Bounce elimination switch :
Mechanical switches are employed in digital system as a input devices by witch digital information (0 and 1) is entered into the system. There is a very serious problem associated with these switches which is switch bouncing (chattering).
If we entered input as ‘1’ in a sequential circuit the output is ‘1’ but it oscillates between ‘1’and ‘0’ before come to rest i.e. 1. This changes the output of the sequential circuit and creates difficulties. This problem is eliminated by the use of Bounce elimination switches.
B) Registers :
A register is composed of a group of flip-flops to store a group of bits (word). For storing N bit of words we require N number of flip-flops (one flip of for each bit).
C) Counters :
Digital counters are used for count the events. Electrical pulses corresponding to the event are produced using transducers & these pulses counted using a counter.
D) Random access memory:
In computers, digital control systems, information processing systems it is necessary to store digital data and retrieve the data as desired.
Flip-Flops can be used for making memories in which data can be stored for any desired length of time and then readout whenever required.
