Detailed Description

One contiguous approximation band for an equiripple design.

Bands are half-open requirements on the signed zero-phase amplitude, given in radians/sample on [0, pi] like FirDesignPoint::omega. Frequencies between bands are transition regions: they are not approximated and not weighted.

Member Data Documentation

◆ amplitude

double pulp::signal::FirEquirippleBand::amplitude = 0.0

Desired signed zero-phase amplitude across the band.

◆ lower_omega

double pulp::signal::FirEquirippleBand::lower_omega = 0.0

◆ upper_omega

double pulp::signal::FirEquirippleBand::upper_omega = 0.0

◆ weight

double pulp::signal::FirEquirippleBand::weight = 1.0

Positive weight.

The exchange equalizes weight * |A(w) - amplitude|, so a band weighted k times higher converges to k times smaller ripple.
