What is frequency bin in FFT?
frequency bins are intervals between samples in frequency domain. For example, if your sample rate is 100 Hz and your FFT size is 100, then you have 100 points between [0 100) Hz. Therefore, you divide the entire 100 Hz range into 100 intervals, like 0-1 Hz, 1-2 Hz, and so on.
What is a bin center?
A Bin Center is a drop off facility that is smaller than a public warehouse. Often operated by a third-party logistics provider, the bin center serves as a consolidation point for smaller shipments or overflow from an existing warehouse.
