A portable SoC-based ECG-system for 24h x 7d operating time
A portable battery powered 3-channel ECG-system is presented. This system can be operated up to 10 days by two standard AA batteries. It acquires 3 ECG signals with 16 bit resolution using a dedicated system on chip (SoC) with an embedded DSP for power efficient data handling. The digitized data are...

description | A portable battery powered 3-channel ECG-system is presented. This system can be operated up to 10 days by two standard AA batteries. It acquires 3 ECG signals with 16 bit resolution using a dedicated system on chip (SoC) with an embedded DSP for power efficient data handling. The digitized data are filtered with an 80 th order FIR filter and stored on a compact flash (CF) card that can be read out using a standard PC operating system. Combining high performance analog parts for signal acquisition and a powerful DSP on a single chip opens up innovative possibilities in reduction of system size and power consumption. |
