Transfer Function
Since the input and output signals are defined as and
, respectively, the transfer function of this analog
filter is given by, using voltage divider rule,
![$\displaystyle H(s) = \frac{V_C(s)}{V_e(s)}
= \frac{\frac{1}{Cs}}{R+\frac{1}{Cs...
...{RC}\frac{1}{s+\frac{1}{RC}}
\isdef \frac{1}{\tau} \frac{1}{s+\frac{1}{\tau}}.
