Detailed Description

template<typename SampleType = float>
class pulp::signal::WaveguideReflectionFilterT< SampleType >

A passive boundary filter with H(z) = g (1 - a) / (1 - a z^-1).

The sign of g selects open-end (negative) or rigid-end (positive) reflection. For the legal ranges, |H| <= |g| < 1 at every frequency. Every operation is bounded, lock-free, and allocation-free.
