More context needed. Are both related? https://de.mathworks.com/matlabcentral/answers/2048532-how-to-find-time-of-rising-and-falling-edges

Hi Jose,

I understand that you are interested in calculating the peak power of a pulse train in dBm.

The power of any signal is defined by the square of the rms of the signal. To obtain this, you need to follow the below steps:

1. Connect the signal to a "RMS" block.
2. Connect the output of the "RMS" block to a "Math Function" block and select the "square" function.
3. The output of the "Math Function" block is the instantaneous power of the signal. If you want to find the peak power, then use the "MinMax Running Resettable" block to obtain the maximum power. The documentation for the "MinMax Running Resettable" block is available at the following link: https://www.mathworks.com/help/simulink/slref/minmaxrunningresettable.html
4. You can further get the power in dBm using the log function of the "Math Function" block.

Hope this helps!
