Frequecny resolution of FFT is decided by FFT clock frequency

WebJul 20, 2011 · Resolution is 1 / T, where T is the duration of your FFT window. So if you sample for 62.5 ms then your maximum resolution is 16 Hz (i.e. each FFT bin is 16 Hz wide) if your FFT is the same size as your sampling interval (1024 samples). Webbandwidth of the spectrum and that for a given sampling frequency, the number of points acquired in the time-domain signal record determine the resolution frequency.

Only spectral components separated by a frequency larger than the …

WebThe frequency resolution of each spectral line is equal to the Sampling Rate divided by the FFT size. For instance, if the FFT size is 1024 and the Sampling Rate is 8192, the resolution of each spectral line will be: 8192 / 1024 = 8 Hz. Larger FFT sizes provide higher spectral resolution but take longer to compute. WebSpecific to FFT Analyzer. Input size. How much samples to take to analyze audio. Higher values means finer frequency resolution but with bad temporal resolution and vice versa. Defaults to 4410 samples (100ms at 44.1kHz sample rate). FFT size. Buffer size for FFT, which determines the number of bins to visualize.
