1 Answer

Answer :

The  binary  information  in  a  register  can  be  moved from  stage  to  stage  within  the  register  or  into  or  out  of  the  register  upon  application  of  clock  pulses.  This  type  of  bit movement  or  shifting  is  essential  for  certain  arithmetic  and  logic  operations  used  in microprocessors. This gives rise to group of registers called shift registers.

Define race around condition.

Description : Define race around condition.

Last Answer : In JK flip-flop output is fed back to the input. Therefore change in the output results change in the input. Due to this in the positive half of the clock pulse if both J and K are high then output toggles continuously. This condition iscalled ‘race around condition’.
