EquirippleFilterKernel
EquirippleFilterKernel[{{{ωL1,ωR1},{ωL2,ωR2},…},{a1,a2,…}},n] creates a finite impulse response (FIR) filter kernel of length n with an equiripple amplitude response, given the specified left and right band edge frequencies {ωLi,ωRi} and amplitudes ai.
EquirippleFilterKernel[{{{ωL1,ωR1},{ωL2,ωR2},…},{a1,a2,…},{w1,…}},n] uses relative weights wi for each frequency band.
EquirippleFilterKernel[{"type",{{{ωL1,ωR1},…},…}},n] creates a filter of the specified "type".
