Struct FilterConfig 

pub struct FilterConfig {
    pub num_filter: usize,
    pub auto_reset: bool,
    pub filter_callbacks: usize,
    pub oc: [f64; 4],
    pub fc: [f64; 4],
    pub rc: [f64; 2],
    pub o_offset: f64,
    pub o_scale: f64,
    pub f_offset: f64,
    pub f_scale: f64,
}

4-tap recursive filter configuration.

Filter step: F_n = FC1I_n + FC2F_{n-1} + FC3*(F_{n-2} - FOffset) + FC4*(F_{n-3} - FOffset) F_n = FOffset + FScale * F_n

Output step: O_n = OC1F_n + OC2F_{n-1} + OC3*(O_{n-1} - OOffset) + OC4*(O_{n-2} - OOffset) O_n = OOffset + OScale * O_n

Reset (first frame or auto-reset): F_0 = RC1 * I + RC2 * F_prev (F_prev = 0 initially)

Fields

num_filter: usize

Number of frames to average before auto-reset (if enabled).

auto_reset: bool

Automatically reset the filter when num_filtered reaches num_filter.

filter_callbacks: usize

Output every N frames (0 = every frame).

oc: [f64; 4]

Output coefficients [OC1, OC2, OC3, OC4].

fc: [f64; 4]

Filter coefficients [FC1, FC2, FC3, FC4].

rc: [f64; 2]

Reset coefficients [RC1, RC2].

o_offset: f64

Output offset.

o_scale: f64

Output scale.

f_offset: f64

Filter offset.

f_scale: f64

Filter scale.
