Detailed Description

Everything designed for one tape speed: the gap FIR (speed-only) and the scaled IIR parameters, which are a pure function of geometry once the dimensionless shapes are fitted.

empty()

bool pulp::signal::chardelay::TapeLossDesign::empty ( ) const

gap_group_delay_samples()

double pulp::signal::chardelay::TapeLossDesign::gap_group_delay_samples ( ) const

gap_taps()

const std::vector< double > & pulp::signal::chardelay::TapeLossDesign::gap_taps ( ) const

geometry_at()

TapeLossGeometry pulp::signal::chardelay::TapeLossDesign::geometry_at ( double age ) const

inlinenoexcept

The geometry at a given age: spacing walks the age table, everything else is fixed.

parameters_at()

TapeLossIirParams pulp::signal::chardelay::TapeLossDesign::parameters_at ( double age ) const

inlinenoexcept

Filter parameters at age.

Exact at every age — a scalar multiply of a fitted shape, not an interpolation between fits. Allocation-free.

prepare()

void pulp::signal::chardelay::TapeLossDesign::prepare ( double fs, double speed_ips )

inline

Expensive: fits both dimensionless shapes. Once per instance.

set_speed()

void pulp::signal::chardelay::TapeLossDesign::set_speed ( double speed_ips )

inline

Cheap by comparison: only the gap FIR is redesigned, because only it depends on the speed in a way a scale factor cannot express.

shapes()

const TapeLossShapes & pulp::signal::chardelay::TapeLossDesign::shapes ( ) const

inlinenoexcept

speed_ips()

double pulp::signal::chardelay::TapeLossDesign::speed_ips ( ) const
