A portable 6-channel recording system employing time-division multiplexing with cable or radio-telemetry has been developed. The system is very compact and has proved to be reliable when used in a domestic environment. The use of multiplexing, in general, permits an expansion in the number of available channels and a reduction in equipment and tape costs, while the use of pulse interval modulation, in particular, overcomes tape recording limitations which may be encountered with the more common amplitude modulation techniques.
一种采用时分复用技术、带有电缆或无线电遥测功能的便携式6通道记录系统已被开发出来。该系统非常紧凑，并且在家庭环境中使用时已被证明是可靠的。一般来说，复用技术的使用允许增加可用通道的数量，并降低设备和磁带成本，而特别是脉冲间隔调制的使用克服了使用更常见的调幅技术时可能遇到的磁带记录限制。
