ABSTRACT:
A quasi-adaptive analog equalization method and apparatus for compensating for phase and amplitude degradation of data transmitted over a transmission medium. One embodiment of the present invention includes a first quasi-adaptive equalizer that receives a first set of data, in order to adjust the amplitude and phase of the first set of data to produce a second set of data. The first quasi-adaptive equalizer then supplies the second set of data to a second quasi-adaptive equalizer, which adjusts the amplitude and phase of the second set of data to produce an equalized set of data. As both the first and the second equalizers are quasi-adaptive equalizers, they base the amount of their phase and amplitude compensation on the amplitude of the symbol pulses that the equalization network receives.
