Struct futuresdr::blocks::FirBuilder

pub struct FirBuilder {}

Create a Fir filter.

Uses futuredsp to pick the optimal FIR implementation for the given constraints.

Note that there must be an implementation of futuredsp::TapsAccessor for the taps object you pass in, see docs for details.

Additionally, there must be an available core (implementation of futuredsp::UnaryKernel) available for the specified SampleType and TapsType. See the futuredsp docs for available implementations.

Usage

use futuresdr::blocks::FirBuilder;
use futuresdr::runtime::Flowgraph;
use num_complex::Complex;

let mut fg = Flowgraph::new();

let fir = fg.add_block(FirBuilder::new::<f32, f32, f32, [f32; 3]>([1.0, 2.0, 3.0]));
let fir = fg.add_block(FirBuilder::new::<Complex<f32>, Complex<f32>, f32, _>(&[1.0f32, 2.0, 3.0]));
let fir = fg.add_block(FirBuilder::new::<f32, f32, f32, Vec<f32>>(vec![1.0, 2.0, 3.0]));

let fir = fg.add_block(FirBuilder::new_resampling_with_taps::<f32, f32, f32, _>(3, 2, vec![1.0f32, 2.0, 3.0]));

Implementations

impl FirBuilder

pub fn new<InputType, OutputType, TapType, Taps>(taps: Taps) -> Blockwhere InputType: 'static + Send, OutputType: 'static + Send, TapType: 'static + Send, Taps: 'static + TapsAccessor<TapType = TapType> + Send, NonResamplingFirKernel<InputType, OutputType, Taps, TapType>: UnaryKernel<InputType, OutputType> + Send,

Create a new non-resampling FIR filter with the specified taps.

pub fn new_resampling<InputType, OutputType>( interp: usize, decim: usize ) -> Blockwhere InputType: 'static + Send, OutputType: 'static + Send, PolyphaseResamplingFirKernel<InputType, OutputType, Vec<f32>, f32>: UnaryKernel<InputType, OutputType>,

Create a new rationally resampling FIR filter that changes the sampling rate by a factor interp/decim. The interpolation filter is constructed using default parameters.

pub fn new_resampling_with_taps<InputType, OutputType, TapType, Taps>( interp: usize, decim: usize, taps: Taps ) -> Blockwhere InputType: 'static + Send, OutputType: 'static + Send, TapType: 'static + Send, Taps: 'static + TapsAccessor<TapType = TapType> + Send, PolyphaseResamplingFirKernel<InputType, OutputType, Taps, TapType>: UnaryKernel<InputType, OutputType> + Send,

Create a new rationally resampling FIR filter that changes the sampling rate by a factor interp/decim and uses taps as the interpolation/decimation filter. The length of taps must be divisible by interp.
