TIDA-010071: How to use software to detect PILOT_ADC amplitude?

Hi Expert,

Our customer is reading our TIDA-010071 and have some question. As you can see below, the PILOT_ADC signal output has different amplitude. We can easily use ADC to detect duty cycle changing, but how to detect amplitude change? May you give a quick response? Thanks.
