The response to the controlvoltage of the VCO core circuit presented here is linear; that is to say, volts/Hz.
目前为止频率对于VCO核心电路的控制电压的应答表现出线性特征，也就是说，瓦特／赫兹。

A fairly basic circuit (left as an exercise, but it's not difficult) can take the controlvoltage and output a constant current which is proportional to the voltage.
一个相当基础的电路(留作练习，不过并不难)处理控制电压并输出与电压成比例的恒流。

In the application of above 24V fort current voltage grade controlcircuit, Voltage Alternating and resonant wave interference of input model for Programmable Logic Controllers must be resolved.
