    • A signal having instantaneous voltage values, defined by a peak-to-peak voltage magnitude and a D.C. offset voltage level, is converted into another signal having time corresponding waveform characteristics similar to the unconverted signal but having different instantaneous voltage values defined by a lesser peak-to-peak magnitude and/or another D.C. offset voltage level. This signal conversion is used by a triangle generator of the type employing an integrator, detector/control, and a switch so that triangular waveforms of any desired peak-to-peak magnitude and D.C. offset voltage level are produced independent of detector/control requirements.
    • 具有由峰 - 峰电压幅度和DC偏移电压电平定义的瞬时电压值的信号被转换为具有与未转换信号类似的具有时间对应波形特性但具有由较小峰值定义的不同瞬时电压值的另一信号 峰值幅度和/或另一个DC偏移电压电平。 该信号转换由采用积分器,检测器/控制和开关的三角形发生器使用,使得任何期望的峰 - 峰幅度和直流偏移电压电平的三角波形独立于检测器/控制要求而被产生。

    • A high-voltage-level Miller circuit is employed, with capacitive coupling between the input current source and the amplifying device, and between the output terminal of the amplifying device and the deflection plate being driven. The coupling capacitors and integrating capacitor lie in a feedback loop, which greatly reduces output waveform distortion introduced by these capacitors, permitting the use of much smaller capacitor values. A small grid current provides a low-frequency amplitude constraint which stabilizes the operating point and prevents oscillations which would normally result from the oscillatory phase-shift characteristic produced by the use of the smaller capacitors.
    • 采用高压级米勒电路,在输入电流源和放大装置之间以及放大装置的输出端和偏转板之间的电容耦合被驱动。 耦合电容器和积分电容器位于反馈回路中,大大降低了由这些电容引入的输出波形失真,允许使用更小的电容值。 小电网电流提供了低频振幅约束,其稳定了工作点,并且防止了通过使用较小的电容产生的振荡相移特性通常产生的振荡。
