迄今为止,对于振荡器的频率牵引系数,只有近似的关系式可利用。这里介绍了频率牵引系数的精确推导,推导时主要考虑了振荡器导纳的非线性。还介绍了振荡器非线性对频率牵引范围不对称性的影响。
So far, only approximate relational equations have been available for the frequency traction coefficient of an oscillator. Here we introduce the exact deduction of the frequency traction coefficient. The derivation mainly considers the nonlinearity of the admittance of the oscillator. The effect of oscillator nonlinearity on the asymmetry of frequency traction range is also introduced.
