PRELIMINARY
Figure 13. Dual Tone Alerting Signal(CAS) detection flowchart
1. Find the average value of the PK generation period from the envelope component, and check if it enters
into a specific margin.
2. Use AM waveform characteristics to check if the difference in the BMN level near PK exceeds specific
conditions.
3. Check if each PK
’
s interval is within specific conditions.
