1110 Sequence Detector State Diagram

broken image


Last time, I presented a Verilog code together with Testbench for Sequence Detector using FSM. The sequence being detected was '1011'.

This VHDL project presents a full VHDL code for Moore FSM Sequence Detector. A VHDL Testbench is also provided for simulation. The sequence to be detected is '1001'.

Question: State Diagram For Sequence Detector 1110. This problem has been solved! State diagram for sequence detector 1110. Design of a sequence recognizer ( to detect the sequence101) using mealy FSM. . Step 1: derive the state transition diagram –count sequence: 000, 010, 011, 101, 110. Step 2: derive the state transition table from the state transition.


The Moore FSM state diagram for the sequence detector is shown in the following figure.

VHDL code for Moore FSM Sequence Detector is designed based on Moore FSM's state diagram and block diagram:

Simulation Waveform for Moore FSM Sequence Detector in VHDL:

As shown in the simulation waveform of the VHDL Moore FSM sequence detector, the detector output only goes high when the sequence '1001' is detected.

Summary

Description
English: The state diagrams show that sequence detectors do not necessary fall back to the initial (reset) state whenever wrong symbol is recepted. 110 stays at stage 11 and, thus, detects the pattern as soon as 0 arrives whereas detector of 111 must start over if any 0 arrives. This makes 110 to appear more likely in the stream. The diagram was created intentionally for illustrating the w:Gambler's fallacy, after https://jliszka.github.io/2013/08/12/a-frequentist-approach-to-probability.html using Finite State Machine Designer.
