kaiser
Kaiser-Bessel windowing function.
Syntax
kaiser(vec_expr, alpha)
Argument
- vec_expr
- A valid vector expression.
- alpha
- A larger alpha leads to a windowing function with steeper slopes.
Example

---|---|
x = c1.x
|
Given c1, a curve is created which is the original curve windowed using the Kaiser-Bessel window function, with alpha = 3. |
Comments
The resulting curve is power-normalized, in other words, the root mean square (RMS) of the original curve equals the RMS of the resulting curve. The mean is subtracted from the input before windowing in order to eliminate DC bias.
