The high-gain amplifier further includes a passive filter for removing the low-frequency components. According to another feature, the signal averaging means inlcudes a digital microcomputer providing time-base expansion; and according to a still further feature, the apparatus includes a further amplifier producing trigger pulses to the signal averaging means for triggering same, thereby enabling an optimum electrode configuration to be selected producing optimum triggering. | |
