Both outputs QB and QD are now equal to logic "1" and the output from the NAND gate changes state from logic "1" to a logic "0" level and whose output is also connected to the CLEAR (CLR) inputs of all the J-K Flip-flops
NAND gate gives the output as 0 if the inputs are 1. And this output is used to give the clear for each flip flop in the BCD ripple counter.And the counter starts counting from 0000.
the nand gate is used to clear the flipflops to change it from 1001 to 0000
ReplyDeletein bcd ripple counter from 9 it has to go to zero, to clear that thing we are using nand gate.

ReplyDeletefor clearing the flipflop from 1 and 4 to get the counting from 0000 to 1001 and back to 0000 NAND gate is used
ReplyDeleteso that the clear signal can be fed for 1010 condn....

ReplyDeleteIt is basically used to give its output in the clear conditions for the flip-flops.

ReplyDeleteit is used to clear the flipflop and to change it from 1001 to 0000
ReplyDeleteits used to reset the flip flop when an output of 1010 occurs..
