Abstract

|
|
In this paper, we described the ECG telemetry system via the Public Telephone Line. The system consist of a signal acquisition and measurement section, a signal processing section, and a signal transmission section. It used 8 bits microprocessor. The transmission section is composed of 3 ch. analog modulators and 1 ch.´ digital modem.
Especially, using the digital modem, signal is transmitted with about 50% data reduction ratio by the TP (Turning Point) algorithm. The acoustic coupler or inductive coil for ´linking the public telephone line are used. The speed of the digital modem is 300 baud rate.
The MCBS (Multi Channel Biotelemetry System) is tested and evaluated through the experiment...
