if i have a signal with incresing amplitude, how can i detect the peak with the lowest amplitude ?

i am sorry i don't have the data with me but my graph looks like an AM modulation curve so how can i just take the peak with the smallest amplitude ??

You can use findpeaks() in the Signal Processing Toolbox to find all the peaks, then from all the peaks it found, take the one with the lowest height.

thanks for your reply, i really appreciate it , one more thing is there any other way for doing it as i dont have Signal processing tool at this moment ?
