And realize the proportional input signal of the output shaft's position control.

以实现输入信号成比例的输出轴的位置控制。

The theory research results of one cycle controlled switching power amplifier show that the output signal follow the input signal linearly, and the control performance is decided by output filter.

理论分析结果表明，单周控制开关功率放大器的输出信号与输入信号成线性变化关系，其控制性能由输出滤波器决定。

Input is just as unconventional: a Control Core turns NES-compatible gamepads into signal generators that can be used just as easily for music making as for playing.
