Enum rfmod::DspFftWindow
[−]
[src]
#[repr(C)]pub enum DspFftWindow { Rect, Triangle, Hamming, Hanning, BlackMan, BlackManHarris, Max, ForceInt, }
List of windowing methods used in spectrum analysis to reduce leakage / transient signals intefering with the analysis. This is a problem with analysis of continuous signals that only have a small portion of the signal sample (the fft window size). Windowing the signal with a curve or triangle tapers the sides of the fft window to help alleviate this problem.
Variants
Rect
w[n] = 1.0
Triangle
w[n] = TRI(2n/N)
Hamming
w[n] = 0.54 - (0.46 * COS(n/N) )
Hanning
w[n] = 0.5 * (1.0 - COS(n/N) )
BlackMan
w[n] = 0.42 - (0.5 * COS(n/N) ) + (0.08 * COS(2.0 * n/N) )
BlackManHarris
w[n] = 0.35875 - (0.48829 * COS(1.0 * n/N)) + (0.14128 * COS(2.0 * n/N)) - (0.01168 * COS(3.0 * n/N))
Max
Maximum number of FFT window types supported.
ForceInt
Makes sure this enum is signed 32bit.
