What is a bidirectional shift register?
Bidirectional shift registers are the registers which are capable of shifting the data either right or left depending on the mode selected. If the mode selected is 1(high), the data will be shifted towards the right direction and if the mode selected is 0(low), the data will be shifted towards the left direction.
Is SISO bidirectional shift register?
Serial-In Serial-Out Shift Register (SISO) The circuit consists of four D flip-flops which are connected serially. All these flip-flops are synchronous since the same clock signal is applied on each flip flop.
Where are bidirectional shift registers used?
Flip flops can be used to store a single bit of binary data (1or 0). However, to store multiple bits of data, we need multiple flip flops. N flip flops are to be connected to store n bits of data.

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 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.
