改进了的抽头横向延迟线滤波器,可作为部分响应数字数据信号的自动均衡器。部分响应信号,即这种信号脉冲响应的非零取样延伸到不止一个取样周期,用相关比较,由经过均衡器畸变信号的不止一个时间间隔取样而来的误差和极性分量,用来调整各个抽头衰耗器的各个增量。这种多次取样的相对极性,进一步在判决中,考虑是否对给定的抽头衰耗器以增量。
An improved tapped horizontal delay line filter that acts as an auto-equalizer that partially responds to digital data signals. The partial response signal, that is, the non-zero sample of such a signal impulse response, extends to more than one sample period and the correlation and error and polarity components sampled from more than one time interval through which the equalizer distorted signal is used to adjust each Each increment of tap attenuator. The relative polarity of this multiple sampling, further in the judgment, takes into account whether or not to increment a given tap attenuator.
