Struct EmaFilter 

pub struct EmaFilter { /* private fields */ }

Exponential Moving Average filter state

Implementations

impl EmaFilter

pub const fn new() -> Self

Create new EMA filter with uninitialized state

pub fn apply(&mut self, input: f32, alpha: f32) -> f32

Apply EMA filter: output = alpha * input + (1 - alpha) * previous

First call initializes the filter to the input value.

pub fn reset(&mut self, value: f32)

Reset filter state, seeding it to a known value.

The next apply() call will start from value rather than cold-starting at 0.
