Hey to all, this is probably very easy, but im struggling with it, thanks in advance. I have the spectrum of a signal represented in the image above. I need to select samples from x axis(frequency) where y axis is superior to -140dB.
Basiccaly I want two things, select the samples from x where y is superior to -140 and select y samples where y is superior to -140. I was thinking of using the find function, right?
