The Sinus Cardinal
family of functions (indexed by the family of indices a
> 0
) is defined by
it sees heavy use in signal processing tasks.
By analogy, the Hyperbolic
Sinus Cardinal family of functions (also indexed by the family of
indices a > 0
) is defined by
These two families of functions are composed of entire functions.
These functions (sinc_pi and sinhc_pi) are needed by our implementation of quaternions and octonions.
