Study the figure and explain its functions.

Solution

The Circuit Works as synchronous up counter (Binary)with sequence Qn....Q3 Q2 Q1 Q0,Number of bits depends on no of FlipFlops used.

Working: - From the figure one can understand that J and K inputs of FlipFlop Q0 is connected to Enable Pin ,similarly all other Flipflops J and K inputs tied together and connected to ouput of And gate.

So FliFlop can work in 2 state J=0 and K=0(No Change) or J=1 and K=1(Toggle State)

When Enable =1 The first flipflop is in toggle state assuming all flipflops are in 0000 state intially the Q0 will be 1

after first clock as other J and K\'s=0 other outputs will not change Next clock both Q0 and Q1 will change states and so on for next clocks depending on and gates and produces the sequence as follows

Q3 Q2 Q1 Q0

0 0 0 0

0 0 0 1

0 0 1 0

0 0 1 1

0 1 0 0

0 1 0 1

and so on binary sequence
