1"""Signal integrity analysis module. 

2 

3This module provides S-parameter handling, channel de-embedding, 

4and equalization functions for high-speed serial link analysis.

7Example: 

8 >>> from tracekit.analyzers.signal_integrity import ( 

9 ... load_touchstone, deembed, ffe_equalize, return_loss 

10 ... ) 

11 >>> s_params = load_touchstone("cable.s2p") 

12 >>> clean_trace = deembed(trace, s_params) 

13 >>> rl = return_loss(s_params, frequency=1e9)
