Description
Consider designing a binary digital synchronous sequential circuit as follows.
- The circuit has
inputs and output . - The inputs
represent a character from to encoded as , and . - The output
is when the last two consecutive inputs are or ; otherwise is .
Answer the following questions.
(1) Explain in
(2) Draw a state transition diagram of the circuit in the form of a Mealy graph. Use
(3) The output
(4) Simplify the state transition diagram in (2) so that it has
(5) Create a state transition table from the state transition diagram in (4).
(6) Draw Karnaugh maps from the state transition table in (5).
(7) Simplify the logic as much as possible using the Karnaugh maps in (6), and draw the circuit using MIL simbols shown in the Fig.
