Abstract :
In this paper a special case of non-integer filters - namely bi-fractional filters (BFF) - are considered. Those filters are characterised by three parameters and offer rich possibilities of frequency response shaping. This paper is a continuation of an earlier research and focuses on stable filters with eigenvalues in right complex half plane. Conditions on stability of such filters are presented, their impulse responses are analysed and certain remarks on frequency characteristics are given.
