Struct FilterBankConfig 

pub struct FilterBankConfig {
    pub j_max: usize,
    pub quality_factors: Vec<usize>,
    pub signal_length: usize,
    pub xi0: f64,
    pub sigma: Option<f64>,
}

Configuration for a Morlet wavelet filter bank.

Fields

j_max: usize

Number of octaves (logarithmic scale range)

quality_factors: Vec<usize>

Quality factors per order (wavelets per octave for each scattering order)

signal_length: usize

Length of the input signal

xi0: f64

Center frequency of the mother wavelet (default: PI)

sigma: Option<f64>

Bandwidth parameter sigma (default: computed from Q)

Implementations

impl FilterBankConfig

pub fn new( j_max: usize, quality_factors: Vec<usize>, signal_length: usize, ) -> Self

Create a new filter bank configuration with default parameters.

Arguments

• j_max - Number of octaves

• signal_length - Length of the input signal

pub fn with_xi0(self, xi0: f64) -> Self

Set the center frequency of the mother wavelet.

pub fn with_sigma(self, sigma: f64) -> Self

Set a custom bandwidth parameter.
