A telemetry system has been designed to transmit two channels of wideband activity (0.2 Hz-2.5 KHz) recorded from high-impedance microelectrodes in the brains of free-moving cats. Thus, both unit activity and slow-wave field activity are accessible without disruption of the animals' behavior. In addition, circuitry is described that conditions the receiver signals, that dicriminates valid subcarrier signals from receiver noise and that automatically aborts data output in the absence of discriminable subcarrier. This receiver signal processing circuitry thus assures the fidelity of the decoded subcarrier, greatly facilitates further machine processing of the data and frees the experimenter from having to continuously monitor the receiver signals to subjectively edit out noisy data.
已设计出一种遥测系统，用于传输从自由活动的猫脑内高阻抗微电极记录到的两个通道的宽带活动（0.2赫兹 - 2.5千赫兹）。这样，在不干扰动物行为的情况下，既可以获取单位活动，也可以获取慢波场活动。此外，还描述了一种电路，该电路对接收信号进行调节，从接收噪声中辨别出有效的副载波信号，并在没有可辨别的副载波时自动中止数据输出。因此，这种接收信号处理电路确保了解码副载波的保真度，极大地促进了对数据的进一步机器处理，并使实验者无需持续监测接收信号来主观地剔除噪声数据。
