Higher Study | Digital Electronics | Multivibrators

Two monoshot multivibrators, are positive edge triggered (M1) and another negative edge triggered (M2), are connected as shown in figure The monoshots M1 and M2 when triggered produce pulses of width T1 and T2 respectively, where T1 > T2. The steady state output voltage v0 of the circuit is
