Abstract
An equalizing circuit, for compensating frequency response perturbations in a loudspeaker caused by a recessed mounting of the loudspeaker, includes an input for receiving an audio signal, a peaking network coupled to the input for augmenting the audio signal in a first frequency range, a dipping network also coupled to the input for attenuating the audio signal in a second frequency range, and a combiner for combining an output of the peaking network to an output of the dipping network, an output of the combiner carrying a compensated audio signal for application to the loudspeaker.
Claims19
A television receiver comprising:
- a tuner for receiving and tuning to a television signal;
- a video signal processing circuit coupled to a first output of said tuner for processing a video component of said television signal, said video signal processing circuit generating at least one display signal;
- display means coupled to said video signal processing circuit for displaying said at least one display signal;
- synchronizing signal generating means also coupled to said first output of said tuner for generating synchronizing signals for controlling said display means;
- an audio signal processing circuit coupled to a second output of said tuner for processing an audio component of said television signal;
- said audio signal processing circuit generating at least one audio signal;
- at least one loudspeaker coupled to an output of said audio signal processing circuit for reproducing the at least one audio signal;
- a cabinet within which at least said at least one loudspeaker is mounted;
- and
- an equalizing circuit for compensating frequency response perturbations in said at least one loudspeaker caused by a recessed mounting of said at least one loudspeaker in said cabinet, said equalizing circuit comprising:
- an input for receiving the audio signal;
- a peaking network coupled to said input for augmenting the audio signal in a first frequency range;
- a dipping network coupled to said input for attenuating the audio signal in a second frequency range;
- and
- means for combining an output of said peaking network to an output of said dipping network, an output of said combining means carrying a compensated audio signal for application to said loudspeaker.
