Length Of The Fft Window at Angela Mercier blog

Length Of The Fft Window. Although performing an fft on a signal can provide great insight, it is important to know the limitations of the fft and how to improve the. Compare six common windows and. If you have a signal containing 2 sine. Resolution is 1 / t, where t is the duration of your fft window. If your signal is stationary and perfectly periodic, then you can get the amplitude by using a data and fft length that are exactly an integer multiple of the signal's period, and using no window. Your bin resolution is just fsamp n f s a m p n, where fsamp f s a m p. It really depends on what you want to do with your signal. Learn how windows affect the fourier transform of data by using graphical convolution, drawings, and examples. This is may be the easier way to explain it conceptually but simplified: So, what is the right fft size? If you sample for 62.5 ms, then your maximum resolution is 16. This post will detail the properties in terms of main lobe size and side lobe level for commonly used windows, such as the rectangular.
