    • A channel in a telemetry system is described. The channel includes a sample-and-hold circuit, a variable resistor circuit, and a control element. The sample-and-hold circuit is configured to hold a sample of a signal. The variable resistor circuit is communicatively coupled to the sample-and-hold circuit, and is configured to present a variable impedance to one or more signal lines during a time period designated for the channel. The variable impedance is representative of the sample held by the sample-and-hold circuit. The control element is configured to control the variable resistor circuit to present to the one or more signal lines an open circuit equivalent impedance during times other than the time period designated for the channel.
    • 描述遥测系统中的一个通道。 通道包括采样保持电路,可变电阻电路和控制元件。 采样和保持电路被配置为保持信号的采样。 可变电阻器电路通信地耦合到采样和保持电路,并且被配置为在为信道指定的时间段期间向一个或多个信号线呈现可变阻抗。 可变阻抗代表由采样保持电路保持的采样。 控制元件被配置为控制可变电阻器电路在除了为通道指定的时间段之外的时间期间向一个或多个信号线呈现开路等效阻抗。
