Abstract
The two input Griffiths-Jim acoustic beamformer is analysed in the frequency domain using
a Wiener type formulation. Unlike previous solutions the approach here is to look at the
problem of non-minimum phase acoustic transfer functions which are encountered in many
real filtering problems. The polynomial transfer function approach gives an elegant way of
obtaining the frequency response of the beamformer and gives new insight to the problem
in general.
