Such a group of flip-flop is known as a Register. The n-bit register will consist of n number of flip-flop and it is capable of storing an n-bit word. The binary data in a register can be moved within the register from one flip-flop to another. The registers that allow such data transfers are called as shift registers.

What are the types of flip flops?
There are basically four different types of flip flops and these are:
- Set-Reset (SR) flip-flop or Latch.
- JK flip-flop.
- D (Data or Delay) flip-flop.
- T (Toggle) flip-flop.
What is a register in a circuit?
Registers are groups of flip-flops , where each flip-flop is capable of storing one bit of information. An n-bit register is a group of n flip-flops. The basic function of a register is to hold information in a digital system and make it available to the logic elements for the computing process.
Is register a sequential circuit?
These sequential logic circuit elements are grouped together to form registers. The circuit changes state from the present state to the next state on a clock control input (as happens in a synchronous sequential logic circuit).
What is the difference between register and counter?
Register – is a group of flip-flops. … Counter – is essentially a register that goes through a predetermined sequence of states. The gates in the counter are connected in such a way as to produce the prescribed sequence of binary states.
What is the application of T flip flop?
The T or «toggle» flip-flop changes its output on each clock edge, giving an output which is half the frequency of the signal to the T input. It is useful for constructing binary counters, frequency dividers, and general binary addition devices.
What are the applications of JK flip flop?
Applications of JK Flip Flop
- Registers. A single flip flop can store a 1 bit word. …
- Counters. Counter is a digital circuit used for a counting pulses or number of events and it is the widest application of flip-flops . …
- Event Detectors. …
- Data Synchronizers. …
- Frequency Divider.

Which flip flop is used in register?
A simple Shift Register can be made using only D-type flip-Flops, one flip-Flop for each data bit. The output from each flip-Flop is connected to the D input of the flip-flop at its right. Shift registers hold the data in their memory which is moved or “shifted” to their required positions on each clock pulse.
What is the difference between register and shift register?
With registers, data can be fed one bit at a time (serially) or can be loaded in a batch all at the same time (in parallel). Shift registers can serve as data storage spaces or data movement devices. They are therefore commonly implemented in devices such as calculators or computers.
Can a shift register be used as a counter?
Shift registers are also used as counters. There are two types of counters based on the type of output from right most D flip-flop is connected to the serial input. Those are Ring counter and Johnson Ring counter.
Why clock is used in sequential circuits?
Clock signals control the outputs of the sequential circuit . That is it determines when and how the memory elements change their outputs . If a sequential circuit is not having any clock signal as input, the output of the circuit will change randomly.
What are the different types of shift register counter?
Basically, these registers are classified into four types and working of shift registers are discussed below.
- Serial in Serial out (SISO) Shift Register.
- Serial in parallel out (SIPO) Shift Register.
- Parallel in Serial out (PISO) Shift Register.
- Parallel in Parallel out (PIPO) Shift Register.
Why flip flop is called latch?
When an input is used to flip one gate (make it go high), the other gate will flop (go low). Hence, «flip flop». … When the clock input is in the state to enable the first latch, that latch will track the state of the input, but the second D latch will hold whatever it’s holding at the moment.
What are the applications of shift register?
Applications of shift Registers –
The shift registers are used for temporary data storage. The shift registers are also used for data transfer and data manipulation. The serial-in serial-out and parallel-in parallel-out shift registers are used to produce time delay to digital circuits.
Where is counter used?
Counters are used not only for counting but also for measuring frequency and time ; increment memory addresses . Counters are specially designed synchronous sequential circuits, in which , the state of the counter is equal to the count held in the circuit by the flip flops.
