How many times has a circuit been designed using typical values, only to find that the circuit does not work because the device used is not typical?
有多少次是根据典型值设计好电路后却发现只是因为使用的器件不典型而不能工作呢？

If the selected voltage transfer function circuit is not sensitive to stray capacitance, then the implemented simulation impedance circuit is also not sensitive to stray capacitance.
如果所选用的电压传递函数电路对杂散电容不灵敏，那么实现的模拟阻抗电路对杂散电容也是不灵敏的。

Coding circuit inside (may not code), can be connected in alarm bus directly when coded and matched with module when not coded.
