Abstract

A versatile visual pattern generator is described that can be programmed by a microcomputer and is developed as a part of a portable visual evoked potential analysis system. The hardware is contained on one printed circuit board (3" X 10", 7.5 X 25.5 cm) residing in an interface connector of a microcomputer (Apple II). The generator produces signals for commercial 50 Hz video monitors; a calibration procedure based on a photocell measurement corrects for the non-linear voltage intensity characteristic of the phosphor of the video monitor.

摘要

本文描述了一种通用视觉模式发生器，它可以由微型计算机编程，并作为便携式视觉诱发电位分析系统的一部分开发。硬件包含在一块印刷电路板（3英寸×10英寸，7.5×25.5厘米）上，该电路板位于微型计算机（苹果II型）的接口连接器中。该发生器为商用50Hz视频监视器产生信号；基于光电池测量的校准程序可校正视频监视器荧光粉的非线性电压强度特性。
