患者泄漏电流限制
摘要：
一种基带接收器，其由接收器输入端口组成，所述接收器输入端口被配置为接收响应于人类患者组织中的电活动而生成的基带信号。所述接收器包括：调制器，其被配置为用所述基带信号对本地振荡器信号进行调制；以及隔离装置，其被配置为在所述装置的输入端口处接收调制的本地振荡器信号，且作为响应，在所述装置的输出端口处生成调制的输出本地振荡器信号。所述接收器还包括解调器，其被配置为用所述本地振荡器信号对所述调制的输出本地振荡器信号进行解调，以便恢复所述基带信号。
摘要（英）：

A baseband receiver, consisting of a receiver input port, configured to receive a baseband signal generated in response to electrical activity in tissue of a human patient. The receiver includes a modulator, configured to modulate a local oscillator signal with the baseband signal, and an isolating device configured to receive the modulated local oscillator signal at an input port of the device and in response to generate a modulated output local oscillator signal at an output port of the device. The receiver further includes a demodulator configured to demodulate the modulated output local oscillator signal with the local oscillator signal so as to recover the baseband signal.
