Variable fractional delay (VFD) filter design has become increasingly significant in digital signal processing, offering the flexibility to delay signals by non-integer amounts. This technology is ...

derivation, and presents the FSD filter's properties. Additionally, we present and discuss illustrative examples of optimal FSD filters.

A new generation of wideband amplifiers and multipliers allows you to build state-variable active filters that operate beyond the kilohertz region into the megahertz region. Using these devices and ...
