$I_a(t)=-J_a\sum_0^{\infty} e^{-\frac{nT+t}{\tau_a}}$ for $t \in [nT, (n+1)T]$,这个求和号是对谁求和?对n吗?但是n不是一个给定的数吗?(for $t \in [nT, (n+1)T]$)

Yue9Shang commented 11 months ago

Just a glance, 我感觉可能是对n求和,然后后面的这个范围的n是个typo,本意可能是告诉我们Ia是关于t是周期函数

That's right. It should be $I_a(t)=-Ja\sum{n=0} ^{\infty} e^{-\frac{nT+t}{\tau_a}}$ for $t \in [0, T)$. Thanks for pointing this out.
