A unity feedback system has open-loop transfer function:
\(G\left( s \right) = \frac{{K\left( {1 + 0.5s} \right)\left( {s + 1} \right)}}{{\left( {1 + 10s} \right)\left( {s - 1} \right)}};K > 0\)
The Nyquist plot for the system is shown below.
For the system to be stable, the gain K must be greater than _______.Enter numerical value using the virtual keypad. Round off where necessary.
