“…The following state variable filter
, and complex exponential function
are adopted for the subsequent applications:
Note that the proposed structure requires a single tuning parameter
subject to the constraint (), although alternative approaches to state variable filters, such as, for example, generalized Poisson moment functional or Laguerre filters in all‐pass domain, can be also considered
29,30 . It is worthy of note that a sufficiently large dwell time
allows for the cut‐off frequency of
to emphasize the system's frequency band of interest.…”
