1. How do you define "phase shift" for complex waveforms?
You don't. That's why we talk about 'group delay' instead.
2. How do you create "phase shift" for complex waveforms?
Pass it through an all-pass filer. Different frequencies that all go
in starting at the same time will come out at different times. This is
why things with "phase shift" (note the quotes) are sometimes
described as "smeary."
