Hi Aabid
I would suggest u to crack it by using a matlab component and program your algorithm of how u want to select your power signals and set the threshold in the Program itself. But before writing a code i would suggest u to analyse the signals from adaptive filter and then make the code accordingly. moreover do take care to mention the ports of your matlab component respectively in the code itself. You can easily us ‘if’, ‘else’ commands to carry on your code. That is always an easiest way out.
