I have a lot of arrays, which is sampled at 128 Hz (that means the two consecutive values from the array have a time gap of 1/128 seconds).
Each array contains for about 70 values.
How can I display the spectrum analyzer (in frequency domain) of that array? Especially, how to bandpass filter that array and check the output array with its spectrum?
To check this, I can generate some sine-wave arrays of different frequencies and amplitudes in Labview > Signal Processing > Signal Generator > Sine wave, then sum all the arrays to have a signal arrays of different frequencies. But I don't know how to view its frequency domain and bandpass filter it.
Thanks in advanced.
