A Sequence Detector is a circuit which given an input string of bits generates an output 1 whenever the target sequence (pattern) has been detected. There are two types of sequence detectors: Overlapping: The detector allows overlapping, hence the final bits of one sequence can be the start of another sequence. Non-overlapping: The detector does not allow overlapping, hence a new sequence starts only after the previous sequence is completed.

Transcribed Image Text:A Sequence Detector is a circuit which given an input string of bits generates
an output 1 whenever the target sequence (pattern) has been detected. There
are two types of sequence detectors:
• Overlapping: The detector allows overlapping, hence the final bits of one
sequence can be the start of another sequence.
• Non-overlapping: The detector does not allow overlapping, hence a new
sequence starts only after the previous sequence is completed.
Ex: Detect pattern 101
For non-overlapping case:
Input :0110101011001
Output:0000100010000
For overlapping case:
Input :0110101011001
Output:0000101010000
Design a sequential circuit (overlapping) with an input 'x' the pattern to bel
detected is 01010
For this circuit:
1. Draw the ASM diagram.
2. Construct the state table.
3. Draw the logic circuit for the datapath and control in logisim.
