    摘要: A hybrid amplifier for connecting a signal carrying line to a repeater. The hybrid includes an autotransformer having a center tap dividing it into two portions. The signal carrying line, an amplifier section, a terminating resistor, and a feedback network are connected to the autotransformer in such a manner that the signal carrying line and the feedback network form a first conjugate pair and the amplifier section and the terminating resistor form a second conjugate pair.

    摘要: An improved active type group-delay equalizer having the transfer function

    摘要翻译: 具有传递函数N =(AZb + AZa + B / CZb-DZa + E)的改进的有源类型组延迟均衡器,其中A,B和D对于给定的AZa和Zb是Z1和Z2的函数,使得N =常数 。 通过选择Za和Zb都具有反应分量来实现幅度失真的附加减小。
