Traditional design of
digital filters
§The processing filters hij are
usually computed following
one of several, complex mathematical theories, based on the solution of the wave equation (often under certaing
simplifications), and
assuming that the microphones are ideal and identical
§In some
implementations, the signal of each microphone is processed through a digital filter for compensating its deviation, at the expense
of heavier
computational load
