ABSTRACT:
A method and apparatus for setting the parameters of an equalizer. Equalizers are used for equalizing distorted signals. However, optimum equalization is only achieved when the parameters of the equalizer are optimally set. To set the parameters of an equalizer optimally, the output signal of the equalizer is rectified in a full-wave rectifier. The output signal of the latter is integrated in an integrator. The parameters of the equalizer are set by a microprocessor according to an algorithm. In one embodiment, when the integration time is predetermined, the parameters of the equalizer is changed until the level of the integrated signal becomes a maximum. In another embodiment, when the maximum level of the integrated signal is predetermined, the parameters of the equalizer are changed until the integration time becomes a minimum.
