What is the highest frequency in the FFT?
Fast Fourier Transform
Its algorithm uses a sequence of N number of digital samples, where N is a power of 2.
The highest frequency that the FFT can resolve is the Nyquist frequency so there are N/2 frequency values.What is frequency in FFT size?
The FFT size defines the number of bins used for dividing the window into equal strips, or bins.
Hence, a bin is a spectrum sample , and defines the frequency resolution of the window.
By default : N (Bins) = FFT Size/2.The bandwidth of the FFT is divided into bins, the number of which is 1/2 the FFT length.
The bin width (also called line spacing) defines the frequency resolution of the FFT.
The FFT provides amplitude and phase values for each bin.
The bin width is stated in hertz.
