Consider the building block called ‘Network N’ shown in the figure. Let $C= 100\mu F$ and $R= 10 k \Omega.$

Two such blocks are connected in cascade, as shown in the figure.

The transfer function $\frac{V_{3}(s)}{V_{1}(s)}$ of the cascaded network is

1. $\frac{s}{1+s} \\$
2. $\frac{s^{2}}{1+3s+s^{2}} \\$
3. $\left ( \frac{s}{1+s} \right )^{2} \\$
4. $\frac{s}{2+s}$
