What is Shift register?
A chain of flip-flops that moves data one bit to the next stage on each clock. It is used for serial-parallel conversion and as the scan chain in scan testing.
Field: Logic circuits
Shift register in the explanations
A shift register can accumulate serial data arriving bit by bit on one line and output it in parallel, or do the reverse.
What is a typical use of a shift register, which chains fli…A Johnson counter feeds the inverted last output of a shift register back to its input, cycling through 2n states with n flip-flops (with three: 000→100→110→111→011→001).
How many states does a Johnson (twisted-ring) counter made …
