convergence_tolerance

double pulp::signal::FirEquirippleOptions::convergence_tolerance = 1.0e-8

Relative gap between the grid's peak error and the interpolated ripple below which the exchange is converged.

grid_density

std::size_t pulp::signal::FirEquirippleOptions::grid_density = 16u

Dense-grid points per independent coefficient.

The classic Parks and McClellan value is 16; smaller grids can miss an extremum.

maximum_iterations

std::size_t pulp::signal::FirEquirippleOptions::maximum_iterations = 64u

Bounded exchange budget. Reaching it is reported, never ignored.

maximum_minimax_error

double pulp::signal::FirEquirippleOptions::maximum_minimax_error = 0.0

Optional requirement.

When positive, a converged design whose minimax error exceeds it is rejected as infeasible at this tap count rather than returned as a filter that silently misses the spec.

maximum_workspace_bytes

std::uint64_t pulp::signal::FirEquirippleOptions::maximum_workspace_bytes = kDefaultFirDesignWorkspaceBytes

tap_count

std::size_t pulp::signal::FirEquirippleOptions::tap_count = 0

type

LinearPhaseFirType pulp::signal::FirEquirippleOptions::type = LinearPhaseFirType::type_i_symmetric_odd
