Hello,
I have a signal in frequency domain and my noise frequencies are in the range of 5 to 7kHz. I can not use filter to completely eliminate these band of frequencies but instead of that I would like to put a amplitude threshold on this band of frequencies. Let say, when the amplitude of this band is greater than 0.000002, it would say that it is noise and it the amplitude is less than that should say as good. How can I do that on a frequency spectrum.
