Design a sequential machine that implements a door lock control. The input is a
sequence of digits where every digit is between 0 and 3 inclusive. The door will not open unless
the entered number sequence is 102103.
The input entered is from left to right. First 1 then 0 then 2 then 1 then 0 then 3 => open the
door.
Implement the machine using Moor Model. Use D flip flops. Show all steps of design from
state diagram till block diagram.
PLEASE WHO CAN HELP SOLVING THIS??

Sounds like homework. Thread moved to Homework Help.

Start by showing us what you have designed so far.
