The Complex Order Fractional Derivatives and Systems Are Non Hermitian
Keyword(s):
This paper discusses the concept of fractional derivative with complex order from the application point of view. It is shown that a fractional derivative is hermitian, if and only if the order is real. The hermitian part of complex order derivatives behave like allpass filters with almost logarithmic phase.
