Measuring system, particularly integrated circuit, for monitoring biosignals, has mobile part with multiple channels, and each channel has amplifier stage with two inputs for receiving biosignal, where base station receives measuring data

摘要

The system has a mobile part carried on a body, and a base station (101 to 110) to receive measuring data. The mobile part has multiple channels (1 to 10), where channel has an amplifier stage with an input for receiving a biosignal and another input for receiving a compensating signal. The compensation signal is determined using the biosignal, which is grounded off from the amplifier stage. The mobile part has an analog-digital converter for digitizing the biosignals and a digital microcontroller or a digital signal processor as digital part for processing the digitized biosignals.
