The Bode magnitude plot of a first order stable system is constant with frequency. The asymptotic value of the high frequency phase, for the system, is $-180^{\circ}$. This system has
- one $\text{LHP}$ pole and one $\text{RHP}$ zero at the same frequency.
- one $\text{LHP}$ pole and one $\text{LHP}$ zero at the same frequency.
- two $\text{LHP}$ poles and one $\text{RHP}$ zero.
- two $\text{RHP}$ poles and one $\text{LHP}$ zero.
