Function enbw 

Source 
pub fn enbw(window: Window, n: usize) -> FFTResult<f64>
Expand description

Compute the equivalent noise bandwidth of a window

§Arguments

  • window - Window function
  • n - Window length

§Returns

The equivalent noise bandwidth of the window.

§Examples

use scirs2_fft::window::{Window, enbw};
use approx::assert_relative_eq;

let bandwidth = enbw(Window::Hann, 1024).unwrap();
assert_relative_eq!(bandwidth, 1.5, epsilon = 0.01);

§Errors

Returns an error if the window calculation fails.
