Struct PeriodicResyncConfig 

pub struct PeriodicResyncConfig {
    pub period: u32,
    pub max_drift_ulps: i32,
}

Configuration for periodic fixed-point accumulator resynchronisation.

Usage

At every observation step, call should_resync(obs_count % period). When true, call apply_periodic_resync() on each Q16.16 accumulator that carries a running sum over an extended session.

Default

period = 65536 (one full Q16.16 fractional cycle, ≈ 1 s at 64 kSPS). max_drift_ulps = 32 (½ LSB of a 16-bit ADC ≈ 7.6 × 10⁻⁶).

Examples

use dsfb_rf::fixedpoint::{PeriodicResyncConfig, apply_periodic_resync,
                            quantize_f32};
let cfg = PeriodicResyncConfig { period: 1000, max_drift_ulps: 50 };
let rho_q = quantize_f32(0.10);
let drifted = rho_q + 80;
if cfg.should_resync(999) {
    let (v, _) = apply_periodic_resync(drifted, rho_q, cfg.max_drift_ulps);
    let _ = v; // re-zeroed value
}

Fields

period: u32

Number of observations between resync opportunities.

max_drift_ulps: i32

Maximum allowed accumulator drift in Q16.16 ULPs before correction. 1 ULP = 1/65536 ≈ 1.53 × 10⁻⁵ in f32 terms.

Implementations

impl PeriodicResyncConfig

pub const DEFAULT: Self

Default configuration: period 65536, tolerance 32 ULPs.

pub fn should_resync(&self, obs_mod_period: u32) -> bool

Returns true when obs_mod_period == period - 1 (epoch boundary).

Call as: cfg.should_resync(obs_count % cfg.period).
