The figure above adds the averagevalue filter circuit andJFET on the basis ofthe SVF, andJFET is usedas a variable resistor AGC to achieve steady increasing.
The figure aboveuses the comparator to achieve the AGC, andthe comparator's output voltage range is determined by the average detector . (View)

The two parts' components and model parameters correspond to the same time to get a 1:1 duty cycle square wave , and the frequency RB is Rb1 or Rb2 in the figure, the upper limited value Rb1 <0.5BRc1; Rb2 <0.5 BRc2. Here B is the transistor collector current amplification factor. The lower limited resistance Rb1> 10Rc1; Rb2> 10Rc2. In circuit, the rectangular wave's frequency is 10Hz.
