Struct FirDesign

pub struct FirDesign;

Expand description

FIR filter design methods.

Implementations§

impl FirDesign

pub fn lowpass_windowed( cutoff_norm: f32, num_taps: usize, window: WindowFunction, ) -> FirFilter

Windowed-sinc lowpass FIR design. cutoff_norm is normalized cutoff (0..0.5), where 0.5 = Nyquist.

pub fn highpass_windowed( cutoff_norm: f32, num_taps: usize, window: WindowFunction, ) -> FirFilter

Windowed-sinc highpass FIR design.

pub fn bandpass_windowed( low_norm: f32, high_norm: f32, num_taps: usize, window: WindowFunction, ) -> FirFilter

Windowed-sinc bandpass FIR design.

pub fn bandstop_windowed( low_norm: f32, high_norm: f32, num_taps: usize, window: WindowFunction, ) -> FirFilter

Bandstop (notch) windowed FIR.

pub fn equiripple_lowpass(cutoff_norm: f32, num_taps: usize) -> FirFilter

Parks-McClellan equiripple lowpass approximation. This is a simplified iterative Remez exchange approximation.

pub fn differentiator(num_taps: usize) -> FirFilter

Differentiator FIR (first-order derivative approximation).

pub fn hilbert(num_taps: usize) -> FirFilter

Hilbert transform FIR (90° phase shift).

Blanket Implementations§

impl<T> Any for T
where T: 'static + ?Sized,

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

impl<T> Borrow<T> for T
where T: ?Sized,

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

impl<T> BorrowMut<T> for T
where T: ?Sized,

fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value. Read more

impl<T> Downcast for T
where T: Any,

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

impl<T> DowncastSync for T
where T: Any + Send + Sync,

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Sync + Send>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.

impl<T> From<T> for T

fn from(t: T) -> T

Returns the argument unchanged.

impl<S> FromSample<S> for S

fn from_sample_(s: S) -> S

impl<T> Instrument for T

fn instrument(self, span: Span) -> Instrumented<Self>

Instruments this type with the provided Span, returning an Instrumented wrapper. Read more

fn in_current_span(self) -> Instrumented<Self>

Instruments this type with the current Span, returning an Instrumented wrapper. Read more

impl<T, U> Into<U> for T
where U: From<T>,

fn into(self) -> U

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

impl<T, U> ToSample<U> for T
where U: FromSample<T>,

fn to_sample_(self) -> U

impl<T, U> TryFrom<U> for T
where U: Into<T>,

type Error = Infallible

The type returned in the event of a conversion error.

fn try_from(value: U) -> Result<T, <T as TryFrom<U>>::Error>

Performs the conversion.

impl<T, U> TryInto<U> for T
where U: TryFrom<T>,

type Error = <U as TryFrom<T>>::Error

The type returned in the event of a conversion error.

fn try_into(self) -> Result<U, <U as TryFrom<T>>::Error>

Performs the conversion.

impl<T> WithSubscriber for T

fn with_subscriber<S>(self, subscriber: S) -> WithDispatch<Self>
where S: Into<Dispatch>,

Attaches the provided Subscriber to this type, returning a WithDispatch wrapper. Read more

fn with_current_subscriber(self) -> WithDispatch<Self>

Attaches the current default Subscriber to this type, returning a WithDispatch wrapper. Read more
