摘要：A speech-controlled switching arrangement for communication systems in whichthe speech signals are transmitted in the form of digital signals obtained by codemodulation, comprising a plurality of pulse group analyzers coupled to respectivetransmission channels from which analyzers the output pulses are applied to acomparator circuit after integration for the purpose of generating a switching controlsignal, while each pulse group analyzer is provided with a digitally defined thresholdcharacterizing a given fixed modulation index.
