- I don't really understand what you mean by 'the corresponding imaginary signal'.
- What I know is that the imaginary part of a signal in defined only on a complex
- signal space. And, in this case, the imaginary part of a real signal is 0.
- Thus, the filter is simply a system that produces 0 (am I wrong ?).
