Dear colleagues,
I have two functions f1(x) and f2(x). Using the following formula:
to calculate the results, get: 5.125[units].
I tried to calculate separately by F1=fft(f1) , F2=fft(f2) and then multiply
stems one by one and adding the results. I found two problems:
1 - I have been used Hamming window to minimize noise. The amplitude of each
signal changes and the final results too;
2 - When I change the number of samples, the results change too.
None the results in 1 or 2 are igual or close to 5.125 (this is right).
What am I doing wrong?
Can someone help me?
Thanks a lot.
