Two monoshot multivibrators, one positive edge triggered ($M_1$) and another negative edge triggered ($M_2$), are connected as shown in figure
The monoshots $M_1$ and $M_2$ when triggered produce pulses of width $T_1$ and $T_2$ respectively, where $T_1$>$T_2$. The steady state output voltage $v_0$ of the circuit is
