摘要： The RF signal (11) is partitioned (R4, R3) and subtracted from the left and right audio channels of a multiport circuit, to reduce the crosstalk between the channels due to the presence of the coil L1.
摘要翻译： RF信号（11）被分割（R4，R3）并从多端口电路的左和右音频通道中减去，以减少由于线圈L1的存在而引起的通道之间的串扰。

摘要： A substantially-universal detector of far-end call disconnect- indicative tones detects the foreseeable forms of tone-based signalling of remote-end call disconnect that are likely to be employed anywhere in the world, without reconfiguration or reprogramming for different tones or countries. Implemented in the digital signal processor (DSP 30) of port circuits of switching systems or adjunct processors, the detector determines parameters (204) of signals carried by the call to the near end and uses them, along with already-present linear predictive coding (LPC) predictor coefficients (202) and indications of energy (203) in the signals, in a multivariate classification (230) of call progress tones from other tones. When presence of any call progress tones is thus detected substantially without interruption for a predetermined minimum time in the received signals, the call is considered (240) to have been disconnected at the far end. In response, a voice messaging system (VMS) adjunct processor deletes any recording of the call progress tones from the end of the recorded message.
摘要翻译： 基本上通用的远端呼叫断开检测器 - 指示音调检测可能在世界任何地方使用的远程端呼叫断开的可预见形式的基于音调的信令，而不用针对不同音调或国家重新配置或重新编程。 在交换系统或附属处理器的端口电路的数字信号处理器（DSP 30）中实施，检测器确定由调用传送到近端的信号的参数（204）并将它们与已存在的线性预测编码（ LPC）预测器系数（202）以及信号中的能量（203）的指示中的一个或多个。 当在接收的信号中基本上没有中断地检测到存在任何呼叫进程音时达到预定的最小时间时，认为该呼叫（240）在远端已经断开。 作为响应，语音消息系统（VMS）附件处理器从记录的消息结尾删除任何记录的呼叫进度音。

摘要： Ein Signalisierungsempfänger ist mit seinem Signaleingang (E) in einem Amtsverbindungssatz an eine Amtsleitung (a, b) angeschlossen und weist ein mit einer Taktleitung (TL) verbundenes variables Bandpaßfilter (BP) auf. Der Signaleingang (E) ist über ein Dämpfungsglied (DG) mit einem variablen Hochpaßfilter (HP) verbunden, und das Hochpaßfilter ist an die Taktleitung (TL) und über eine Signalauswerte- und Umsetzeinheit (SE) an das Bandpaßfilter BP angeschlossen. Außerdem ist ein mit der Taktleitung (TL) verbundener Bandbreitenumschalter (BU) mit dem variablen Bandpaßfilter (BP) und dem Dämpfungsglied (DG) verbunden. Die Grenzfrequenz und die Bandmittenfrequenz des Hochpaßfilters (HP) bzw. des Bandpaßfilters (BP) wird je nach zu empfangender Signalfrequenz mit einem Taktsignal entsprechender Frequenz eingestellt, wobei die Grenzfrequenz tiefer als die Bandmittenfrequenz liegt.

摘要： An antenna connector has a wrist-band contact part (1) for attachment to a wrist-band and connection to an antenna therein and for rotatable arrangement on a wrist-watch pin (2), and a wrist-watch contact part (5) for rotatable arrangement on the wrist-watch pin in electric contact with the wrist-band contact part and for connection to electronic means within a wrist-watch.
