Designing an Overlapping Mealy FSM to Detect the Pattern D–X–B–B
1. Problem Statement Design a synchronous Mealy finite-state machine that scans a continuous stream of letters (A, B, C, D) encoded in two bits and asserts y=1 only ...

Design of a FSM two input detector sequence
I'm designing a finite state machine (FSM) that detects the sequences "01011" and "00101" in a serial binary input. When either sequence is detected, the FSM should output (Y1, Y2) ...

Mealy FSM using SR Flip Flops: pattern detector
I was asked to design a Mealy FSM using SR Flip Flops to detect a pattern. It should detect if the pattern is either '1001' or '0110'. I was able to make the state diagram (I have attached the image), ...

For a simple sequence detector, is there a problem with the FSM diagram for unused states?
This is the diagram, and the sequence we are detecting is 1011. The problem did not specify whether it is Mealy or Moore FSM, or whether it is overlapping or non-overlapping. When we get an input of ...

Sequence detector which detects sequences 100 and 111
I need to design a pattern detector that recognizes 100 and 111 bit patterns, even overlapping ones. I drew the state diagram as shown in the image and created the related table Could you tell me if ...

Why does sequence detector for 1100 show the correct output for all input 1100 sequences except one in the beginning?
The code I am using is the following. I am using five states as this is a Moore model, and non-overlapping sequence is assumed. The state logic is correct as far as I can tell. However, when I run it, ...
