摘要：It is the objective of this invention to provide a multichannel digital filter bankcircuit and a method implemented by cascading sub-filters of the recursive type suitablefor graphically equalizing electrical signals received via a communication path. It is also anobjective of this invention to produced equalized signals having minimal distortion ofsignal spectral characteristics including magnitude and phase. The circuit of this inventionis implemented with cascaded connections of first order or second order digital filters. Itis an additional objective of this invention to provide for the programming of theindividual transfer functions of the above digital filters so as to produce unity gain. Thisunity gain case results in an output signal which is an exact replica of the input signal withno delay. This result indicates the minimal distortion introduced by the method of thisinvention.
