Detailed Description

Fit both dimensionless shapes.

Allocating and iterative; control thread only, and only once per instance — after this, every speed and every age is a scalar multiply.

fit()

void pulp::signal::chardelay::TapeLossShapes::fit ( )

inline

Re-derive the shapes from the physics.

Expensive (a multi-start simplex search); this is the offline derivation behind the shipped table, kept so the table can be regenerated and so the acceptance suite can prove the shipped values reproduce it.

parameters_for()

TapeLossIirParams pulp::signal::chardelay::TapeLossShapes::parameters_for ( const TapeLossGeometry & geometry ) const

inlinenoexcept

Corners in hertz for a given geometry.

The spacing shape's normalized variable is f·d/v, so its corners become hertz when multiplied by v/d; the thickness shape's is f·δ/v, so by v/δ. Both are exact.

tabulated()

TapeLossShapes pulp::signal::chardelay::TapeLossShapes::tabulated ( )

inlinestaticnoexcept

The shipped values.
