Article Description

A biotelemetry system based on digital data processing and transmission is implemented. The transmitter digitizes analog physiological signal, converts into serial form, forms a digital data packet by summing data and synchronization information and transmits the packets via an FM transmitter. The receiver side amplifies and pulse-shapes the received data packet, separates the data and synchronization information, converts serial data into 8-bit parallel form and then into analog signal. A special coding method provides high noise immunity and proper synchronization between transmitter and receiver. The system shows a stable and high performance within a distance of 100 m.
