Fields

win: [f32; N]

power: f32

Mean squared

nenbw: f32

Normalized effective noise bandwidth (in bins)

overlap: usize

Optimal overlap

Implementations

impl<const N: usize> Window<N>

pub fn rectangular() -> Self

Rectangular window

pub fn hann() -> Self

Hann window

This is the “numerical” version of the window with period N, win[0] = win[N] (conceptually), specifically win[0] != win[win.len() - 1]. Matplotlib’s matplotlib.mlab.window_hanning() (but not scipy.signal.get_window()) uses the symetric one of period N-1, with win[0] = win[N - 1] = 0 which looses a lot of useful properties (exact nenbw() and power() independent of N, exact optimal overlap etc)

Trait Implementations

impl<const N: usize> Clone for Window<N>

fn clone(&self) -> Window<N>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<const N: usize> Debug for Window<N>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<const N: usize> PartialEq for Window<N>

fn eq(&self, other: &Window<N>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
