Hi, I have taken samples for 3Seconds for both noisy and noiseless 10 pumps and I plotted the data in matlab, because I don't know in labview. Anyway, I have to work with labview later. Now, I had written code in labview that writes some data to pump when if noise is in pump. I have attached my image that from Matlab. I need to exactly want to eliminate the noise in red color images. I have used highpass filter and low pass filter to see the difference in strength in matlab. As in the images until 550Hz, pump original frequencies are mixed with noise(in red color pictures) and after that it really most from noise frequencies. Can someone suggest me to find a way in labview that can differentiate this noise from original frequency.

LabVIEW

You can calculate power from power spectrum, see below.

The power of the signal in a given frequency band can be calculated by integrating over positive and negative frequencies,

$P=\int_{F_1}^{F_2}\,S(f)\,d f + \int_{-F_2}^{-F_1}\,S(f)\,df.$
