Design a synchronous sequential circuit with one input line and one output line that recognizes the input string x = 1111. The circuit is also required to recognize overlapping sequence such that if the input string is x = 1101111111010 then the output will be z = 0000001111000. Use D Flip-Flops. Simulate using MultiSim and attach a simulation printout. really need help with a) flip flop excitation tables b)k-map c) circuit layout
