What are the types of shift register?
With this in mind, we can look at the three main types of shift registers that are commonly used: a serial-in serial-out (SISO) shift register, a serial-in parallel-out (SIPO) shift register, and a parallel-in serial-out (PISO) shift register.
What are the applications of shift register?
The major application of a shift register is to convert between parallel and serial data. Shift registers are also used as keyboard encoders.
What is a shift register circuit?
Shift registers are high-speed circuits. Primarily, a shift register moves bits of data either left or right along a circuit, depending on the circuit’s specific structure. In its simplest form, a shift register takes data in at the first stage and shifts bits one stage left or right as the clock signals the need for a data advance.
What is parallel shift register?
The shift register, which allows parallel input (data is given separately to each flip flop and in a simultaneous manner) and produces a serial output is known as Parallel-In Serial-Out shift register. The logic circuit given below shows a parallel-in-serial-out shift register. The circuit consists of four D flip-flops which are connected.

What is a 4 bit shift register?
4 Bit Shift Register. A shift register (serial-in parallel-out type) consists of a group of flip-flops arranged such that the output of one feeds the input of the next so that the binary numbers stored shift from one flip-flop to the next controlled by a clock pulse. This implementation is a 4-bit shift register utilising d-type flip-flops.
