A seven-channel telemetry system for collection and display of biological data is presented. The system can amplify bioelectrical signals in the range of 2 microV to 200 mV and has a bandwidth of 0.1-80 Hz. After multiplexing, the signals are digitized with a resolution of 8 bits. The data are frequency modulated directly on a VHF transmitter. After receiving the data on a VHF receiver, they are routed directly to the RS232 input connector on the PC. Thereby the advantage of direct communication between the transmitter and the PC can be utilized. Expensive analog equipment is avoided and display of the signals on the PC screen as well as signal analysis can be performed. The system has been tested and was found to be stable and highly reliable.
