The output Y depends only on present state of memory elements.

Therefore, it is a Moore circuit.

To draw state diagram:-

Consider four states of output:-

00,01,10,11

1.Assume AB=0.0

When X=0,

$J_{A}$=B=0	$J_{B}$=A=0
$K_{A}$=B.X’=0.1=0	$K_{B}$=A+X=0+0=0
.·. $A_{n+1}$­=0	.·. B$_{N+1}$=0

.•. Next State=00

When X=1,

$J_{A}$=B=1	$J_{B}$=A=0
$K_{A}$=B.X’=0.0=0	$K_{B}$=A+X=0+1=1
.·. $A_{n+1}$­=0 …
