Consider a stable system with transfer function,$$G(s)=\frac{s^{p}+b_{1}s^{p-1}+\dots +b_{p}}{s^{q}+a_{1}s^{q-1}+\dots +a_{q}}$$, where $b_1, \dots ,b_p$ and $a_1, \dots ,a_q$ are real valued constants.The slope of the Bode log magnitude curve of $G(s)$ converges to $-60 \text{dB/decade}$ as $ω\to \infty$.A possible pair of values for $p$ and $q$ is

  1. $p=0$ and $q=3$
  2. $p=1$ and $q=7$
  3. $p=2$ and $q=3$
  4. $p=3$ and $q=5$
