A multichannel EEG telemetry system utilizing a PCM subcarrier.
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.
