Nyquist plot consider a feed back system where the OLTF is:
$$G(s) = {1 \over {s\left( {2s + 1} \right)\left( {s + 1} \right)}}.$$
Determine the asymptote which the nyquist plot approaches as $$\omega \to 0.$$ Find also the range of 'k' in terms of the cross over frequency $${\omega _{PC}}$$ for stability.
