Bridge Reflectance
The bridge reflectance is needed as part of the loop filter in a digital waveguide model (Chapter 6).
As derived in §C.11.1, the force-wave reflectance of
seen on the string is
where
denotes the wave impedance of the ideal string, and
denotes the resonance frequency in
radians per second. The velocity reflectance is simply minus the
force reflectance (§C.11.1).
