A multichannel personal type telemetry system is described that utilizes PCM encoding for the most effective range with minimum RF bandwidth and noise interference. Recent IC developments (COS MOS) make it possible to implement a sophisticated encoding system (PCM) within the low power and size constraints necessary for a personal biotelemetry system. This system includes low level, high impedance preamplifiers to make the system suitable for EEG recording.
本文描述了一种多通道个人型遥测系统，该系统采用脉冲编码调制（PCM）编码，以在最小射频带宽和噪声干扰的情况下实现最有效的传输范围。近期集成电路（COS MOS）的发展使得在个人生物遥测系统所需的低功耗和小尺寸限制内实现复杂的编码系统（PCM）成为可能。该系统包括低电平、高阻抗前置放大器，以使系统适用于脑电图记录。
