30. Consider the building block called ‘Network N’ shown in the figure.

Let C=100µF and R=10kΩ

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

The transfer function $v_3(s)\over v_1(s)$ of the cascaded network is

(A) $s\over 1+s$

(B) $s^2\over 1+3s+s^2$

(C) $({s\over1+s})^2$

(D) $s\over2+s$
