Synchronous overlapping sequence detector that detects the bit patterns 010 and 1001 using J-K flip flops.
Synchronous overlapping sequence detector that detects the bit pattern 101 using J-K' flip flops (74LS109).
if x,y = 0,0
next state is same state
if x = 0,y = 1
next state is plus 1
if x = 1 ,y = 0
next state is minus 1
if x,y = 1,1
next state reset to 0
