1.A user want to use a system that detects the sequence"0000"in an overlaping fashion.Draw the moore and the mealy state diagram for the system.
2.Write the VHDL code for the above system
3.A user wanta 6-bit counter that has an asynchrone clear.the user can load it with a value.when activated,it has two modes.in mode 1,it can perform increment by 4,in mode 2 it decrement the value by 1.write the VHDL code for the system.
