    • Apparatus receiving step voltage inputs provides an output voltage that moves as a linear ramp from step to step. Each new input causes an amplifying circuit to connect a predetermined potential to an integrator, starting a new ramp. A comparator circuit receives voltages proportional respectively to the input and the ramp output, and when they become equal it stops the ramp. An inverter is automatically connected into the amplifying circuit when needed to change the polarity of the potential to the integrator, and thus to reverse the direction of the ramp. Manual and automatic adjusting and switching means control the operating sequences and parameters.
    • 接收步进电压输入的装置提供一个从一步到一步的线性斜坡移动的输出电压。 每个新的输入使得放大电路将预定电位连接到积分器,开始新的斜坡。 比较器电路接收与输入和斜坡输出成比例的电压,当它们相等时,它停止斜坡。 当需要将反相器自动连接到放大电路中以改变积分器的电位极性,从而反转斜坡的方向。 手动和自动调节和切换意味着控制操作顺序和参数。
