A CARDIO PREAMPLIFIER FOR THE FREE‐ROVING RAT
Psychophysiology, 1965ABSTRACTA transistorized amplifier has been designed with the aim of providing a reliable triggering signal for a cardiotachograph when it is recording from small animals. The frequent base‐line instabilities of the cardio signal caused by the animal's movements are eliminated by the use of a transformer at the input. Direct coupling between the stages
