1"""Jitter analysis module for advanced timing characterization. 

2 

3This module provides IEEE 2414-2020 compliant jitter analysis including 

4decomposition into random and deterministic components, bathtub curves, 

5and jitter spectrum analysis.

8Example: 

9 >>> from tracekit.analyzers.jitter import extract_rj, tj_at_ber, bathtub_curve 

10 >>> rj = extract_rj(tie_data) 

11 >>> tj = tj_at_ber(rj_rms=rj.rj_rms, dj_pp=dj.dj_pp, ber=1e-12) 

12 >>> positions, ber_values = bathtub_curve(tie_data, unit_interval=1e-9)
