A circuit diagram is shown for a semiconductor device to intensify the brightness of an oscilloscope during the rapidly rising and falling phases of signals such as action potentials. Brightening pulses proportional in amplitude to the rate of change in the Y-axis are available for connection to an oscilloscope with an external intensity ('Z') modulation input. The circuit requires one transistor, one dual operational amplifier and two single fast operational amplifiers.
给出了一个半导体器件的电路图，用于在诸如动作电位等信号的快速上升和下降阶段增强示波器的亮度。幅度与Y轴变化率成比例的增亮脉冲可用于连接到具有外部强度（“Z”）调制输入的示波器。该电路需要一个晶体管、一个双运算放大器和两个单快速运算放大器。
