Struct basic_dsp_vector::conv_types::RealFrequencyLinearTableLookup

pub struct RealFrequencyLinearTableLookup<T> where
    T: RealNumber,  { /* fields omitted */ }

Allows to create a lookup table with linear interpolation between table points. This usually speeds up a convolution and sacrifices accuracy.

Methods

impl<T> RealFrequencyLinearTableLookup<T> where
    T: RealNumber, 

fn table(&self) -> &[T]

Allows to inspect the generated lookup table

fn delta(&self) -> T

Gets the delta value which determines the resolution

impl RealFrequencyLinearTableLookup<f32>

fn from_raw_parts(table: &[f32], delta: f32, is_symmetric: bool) -> Self

Creates a lookup table by putting the pieces together.

fn from_conv_function(
    other: &RealFrequencyResponse<f32>,
    delta: f32,
    len: usize
) -> Self

Creates a lookup table from another convolution function. The delta argument can be used to balance performance vs. accuracy.

impl RealFrequencyLinearTableLookup<f64>

fn from_raw_parts(table: &[f64], delta: f64, is_symmetric: bool) -> Self

Creates a lookup table by putting the pieces together.

fn from_conv_function(
    other: &RealFrequencyResponse<f64>,
    delta: f64,
    len: usize
) -> Self

Creates a lookup table from another convolution function. The delta argument can be used to balance performance vs. accuracy.

impl RealFrequencyLinearTableLookup<f32>

fn to_complex(&self) -> ComplexFrequencyLinearTableLookup<f32>

Convert the lookup table into complex number space

impl RealFrequencyLinearTableLookup<f64>

fn to_complex(&self) -> ComplexFrequencyLinearTableLookup<f64>

Convert the lookup table into complex number space

Trait Implementations

impl RealFrequencyResponse<f32> for RealFrequencyLinearTableLookup<f32>

fn is_symmetric(&self) -> bool

Indicates whether this function is symmetric around 0 or not. Symmetry is defined as self.calc(x) == self.calc(-x).

fn calc(&self, x: f32) -> f32

Calculates the convolution for a data point

impl RealFrequencyResponse<f64> for RealFrequencyLinearTableLookup<f64>

fn is_symmetric(&self) -> bool

Indicates whether this function is symmetric around 0 or not. Symmetry is defined as self.calc(x) == self.calc(-x).

fn calc(&self, x: f64) -> f64

Calculates the convolution for a data point
