A shifter is a combinational circuit with one or more inputs and an equal number of outputs.
Combinational circuit is a circuit in which we combine the different gates in the circuit for example encoder decoder multiplexer and demultiplexer.
Shifters and shifting author.
The circuit output is equal to 1 if the two numbers are e.

In this part of the lab you will design a circuit that implements an 4 bit circular barrel shifter.
The 4 bit circular barrel shifter is usually implemented by stacking two layers of 2 to 1 multiplexers as shown below.
Also a 4 bit reversible serial in serial out 4 bit r eversible s erial in p arallel o ut 4 bit reversible parallel in serial out and a 4 bit reversible parallel in parallel out shift registers are designed using the proposed d flip flop.
The outputs are shifted with respect to the inputs.
