II$.$ Answer the below. $(110$ points $=10$ points$)$

Explain JK Flipflop. Draw the JK flipflop logic structure

with equivalent symbol.

Design a $3-$bit synchronous binary counter using j$-$k flip$-$

flops.

Hint:

Step $(1)-$ Determine the number of flip$-$flops required

Step $(2)-$ Draw the Logic diagram $($with flipflop Symbols$)$

Step $(3)-$ Draw timing diagram

Step $(4)-$ Obtain the Binary state sequence for JK flipflops used in

the design.
