    摘要: An error reducing arrangement is provided for a signal receiver wherein a sequence of received signals is divided into groups and each group is partitioned into subgroups. A signal representative of the deviations among the signals of each group and a signal representative of the deviations among the signals of each subgroup of said group are generated. Responsive to a subgroup deviation signal exceeding its group deviation signal, the subgroup signals are altered to reduce the subgroup deviations. In this manner errors are reduced without affecting error free signals.

    摘要: A polarity reversal arrangement provided with two seriesarranged electronic switching elements, for example, for use in pulse code modulation. freedom In order to satisfy the strict requirements of polarity reversal at the instants of an alternation of polarity of the signals from a signal source and the requirement of freedom from distortion, the polarity reversal arrangement is provided with a bridge composed of resistors wherein the signal source is connected to one end of a diagonal branch of the bridge and wherein the input circuit of an amplifier reversing the polarity of the input signal is connected to the other end of this diagonal branch and wherein the series arrangement of the two electronic switching elements is included between the ends of the other diagonal branch, the junction of the electronic switching elements being connected to the output circuit of the amplifier, while the output signals of the polarity reversal arrangement are derived from one end of the last-mentioned diagonal branch of the bridge.

    摘要: A sampled data system having improved (sin X)/X correction is provided. A modified switched capacitor filter is used as a receive filter. The switched capacitor filter is modified in a manner to provide a charge gain thereby avoiding the increase in thermal noise normally associated with voltage gain amplification. The modified switched capacitor filter does not impair the dynamic range of the system and can be made duty cycle independent by providing additional controllable switches to the filter.
