A Taste of Linear System Theory and Signal Processing
In the present chapter, we briefly discuss some links between the theory of analytic functions and the theory of linear systems. We refer to the books , , , ,  for more information. The reader should be aware that more recent advances in linear system theory, in the setting of several complex variables, noncommuting variables, or stochastic setting, to name a few, require much more involved tools. Still it is necessary to master the elementary setting outlined here before going to these more advanced areas.
