摘要: This paper describes a peak amplitude selector designed to analyze electrophysiological phenomena ranging from slow (0.1 1 Hz) EEG fast (up 200 kHz) multiple neuronal units. The selector's minimum window height of 10 mV, when used on input signals 0.5 volt allows the selection interesting impulses out group with nearly same amplitude. To increase usefulness, four data outputs are provided: for use recorder, two low speed available? one giving pulse every impulse in window, and pulses (to overcome problem losing counts train is processed by system); high output available; finally, an analog proportional rate arrival provided. In addition, reference supplied display upper lower thresholds relative signal, so that clearly defined. circuit cost components.
