title: High-speed eight-channel thermocouple amplifier.
abstract: An eight-channel thermocouple amplifier system was constructed to measure rapid changes in temperature of only 1 or 2 degrees C simultaneously from many sites within the heart. The system has a response time of less than 5 ms, a resolution of less than 0.025 degrees C, and a voltage gain of approximately 2,500.
