Abstract

In this study, we improve the performance of telemetry ECG modem using acoustic coupler. The results are as follows : (1) General active filter is replaced by SCF(switched capaciror filter) improving the LPF and BPF characteristics. (2) ECG Pre-amplifier is installed in ECG modem. (3) The interface circuit is designed to store the ECG waveform in casette recorder.
