检查一个传统的Hartley振荡器电路就会注意到它的标志:一个带抽头的电感器,它用于确定振荡频率,并提供维持振荡的反馈。尽管可以方便地计算出某个额定频率所需的总感量,但要找到耦合系数k仍有
Examining a conventional Hartley oscillator circuit notices its signature: a tapped inductor that determines the oscillation frequency and provides feedback that maintains oscillation. Although you can easily calculate the total amount of inductance required for a nominal frequency, but to find the coupling coefficient k is still there
