Long-term supervised domiciliary EEG monitoring in epileptic patients employing radio telemetry and telephone telemetry. II. Radio telemetry system.

A miniaturized 8-channel EEG amplifier- submodulator unit is used in combination with a standard radio transmitter/receiver system for long-term ambulatory EEG recording at the patient's residence. The EEG frequency response (0.16-30 Hz) and amplitude range (1:1000) of the system are in accordance with the object in view, the recording of seizures. The submodulator characteristics conform to regulations for radio telemetry.
