The fact that the input resistance can be arranged to be high (100 kD) makes it appear at first sight that this configuration is the most suitable for the input stage of a transistorized biological amplifier; there would be reason- able efficiency of signal transfer from the lower resistance type of electrode system ( nerve lying over silver-wire hooks, large surface electrodes, etc.). Further, the low output resistance makes the configuration appropriate for driving low resistance loads, such as meters. 694.
