Patent ID: 7668237

Claim:
An equalizer arrangement for generating an output signal by equalizing an input signal, comprising: a first equalizer section having a first center frequency f 1 that receives the input signal and provides a first equalizer output signal to a second equalizer section having a second center frequency f 2 that provides a second equalizer output signal; a first correcting equalizer section that receives the second equalizer output signal and has a gain at the first center frequency f 1 equal to the gain of the second equalizer section at the first center frequency f 1 to provide a first correcting equalizer output signal; and a second correcting equalizer section that receives the first correcting equalizer output signal and has a gain at the second center frequency value f 2 equal to the gain of the first equalizer section at the second center frequency f 2 to provide the output signal, where f 1 and f 2 are different values.
