- Physical variables (force, pressure, velocity, ...) are obtained
by summing traveling-wave components.
- To determine the value at any physical point, extract a
physical signal from a digital waveguide using delay-line taps.
- The physical wave vibration is obtained by summing the left- and
right-going traveling waves.
- The two traveling waves in a digital waveguide are now
components of a more general acoustic vibration.
- A traveling wave by itself in one of the delay lines is no
longer regarded as ``physical'' unless the signal in the
opposite-going delay line is zero.
