Abstract:
1. An adaptive signal weighting system including a signal path for transmitting an information signal of a predetermined bandwidth through said system, said system comprising: filter means disposed in said signal path for varying a gain impressed on a portion of said information signal within a first select spectral region within said predetermined bandwidth by a first variable gain factor to provide a filtered signal, said first variable gain factor varying in response to and as a function of a first control signal; means, responsive to said information signal, for generating said first control signal in accordance with a frequency value wherein approximately one-half of the energy of said information signal is below said frequency value; gain control means disposed in said signal path and responsive to said filtered signal for varying signal gain impressed on said filtered signal substantially throughout said predetermined bandwidth by a second variable gain factor to provide an output signal, said second variable gain factor varying in response to and as a function of a second control signal; and means for generating said second control signal in response to and as a function of signal energy of said information signal substantially within a second select spectral region within said predetermined bandwidth.
