Expand description

One-port WDF leaf element (resistor, capacitor, inductor, voltage source).

Leaf elements sit at the ends of the WDF binary tree and interact with the wave domain through incident (a) and reflected (b) waves.

Required Methods§

fn port_resistance(&self) -> f64

Port resistance seen looking into this element (Ω).

fn reflected(&self) -> f64

Produce the reflected wave given the current state.

For resistors: b = 0 (matched termination) For capacitors: b = z⁻¹ a (previous incident) For inductors: b = -z⁻¹ a For voltage sources: b = 2*Vs - a

fn set_incident(&mut self, a: f64)

Accept the incident wave after scatter_down phase.

Reactive elements (C, L) latch this value as state for next sample.

Provided Methods§

fn set_sample_rate(&mut self, _sample_rate: f64)

Update sample rate (for reactive elements C, L).

fn reset(&mut self)

Reset internal state to zero.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
