Analysis of nonminimum phase component on direct transfer function and its inverted transfer function

This paper presents analysis of nonminimum phase component on acoustic transfer function as unknown system when adaptive FIR (finite impulse response) filter is used for noise cancelling scheme. For the application in realistic reverberant environment, nonminimum phase component is analyzed in beamf...
