Abstract:
1. An equalizer system that generates an output signal by equalizing an input signal, comprising: at least two interconnected and mutually interfering equalizers having different center frequencies, where an adjustable gain and an adjustable Q-factor of each of the equalizers at the respective center frequency of the equalizer are controlled by a first group of external control signals; and a non-linear adjustment circuit that generates a first group of internal control signals from the first group of external control signals, where the first group of internal control signals set the gain and the Q-factor of the equalizers at the respective center frequency of each of the equalizers, and where the first group of internal control signals are modified relative to the first group of external control signals such that the adjustable gain and the adjustable Q-factor for at least one of the equalizers is automatically adjusted to reduce interferences occurring between the equalizers.
