Abstract

In contrast with one-channel biotelemetry, multichannel biotelemetry systems permit the analysis of biological systems by means of cybernetics. Some simple examples are given. The basic concept of a multichannel system is described. The criteria of quality of which the nonevident ones are defined by detailing the test circuits are the following (input criteria): number of channels, bandwidth, voltage range, impedance, maximum voltage outside the signal band, stability of the power supply for transducers, factor of safety against multipath propagation, distance between transmitter and receiver, shock, vibration and temperature range, weight, volume and operating time. Output criteria: signal-to-noise ratio, linearity, crosstalk transfer function, different time lags.

摘要

与单通道生物遥测相比，多通道生物遥测系统能够通过控制论对生物系统进行分析。文中给出了一些简单示例。描述了多通道系统的基本概念。通过详细说明测试电路来定义的质量标准（输入标准）如下：通道数量、带宽、电压范围、阻抗、信号带外的最大电压、传感器电源的稳定性、抗多径传播安全系数、发射器与接收器之间的距离、震动、振动和温度范围、重量、体积以及工作时间。输出标准：信噪比、线性度、串扰传递函数、不同的时间延迟。
