4 Bit PIPO
4 Bit PIPOIt's a 4 Bit Parallel In Serial Out (PIPO) shift register. I've used 4 D f/f s here. As it's parallel in so, 4 different inputs are given to each f/f and also 4 different Outputs are there from each f/f s.
Realization:-
When the clock is enable at each positive edged clock pulse the we can get the outputs as the given inputs (i.e if input is 1010 the the output will be also same 1010 after 4 positive edged clock pulse).
