Struct FirFilterBuilder

Source

pub struct FirFilterBuilder<T> { /* private fields */ }

Expand description

Builder for a FIR filter block.

A builder is needed to create a decimating FIR filter block.

Implementations§

Source §

impl<T> FirFilterBuilder<T>
where T: Sample + Mul<T, Output = T> + Add<T, Output = T> + FrequencyTranslate,

Source

pub fn deci(self, deci: usize) -> Self

Set the decimation to the given value.

The default is 1, meaning no decimation.

Source

pub fn build(self, src: ReadStream<T>) -> (FirFilter<T>, ReadStream<T>)

Build a FirFilter with the provided settings.

Source §

impl FirFilterBuilder<Complex>

Source

pub fn translate(self, samp_rate: Float, freq: Float) -> Self

Mix by -freq Hz while filtering.

A tone at freq Hz is translated to DC. The implementation folds the input mixer into the FIR taps and keeps one rotator per output sample.
