Figure 2. Low-pass RL circuit. e-lab: (a) Find an analytical expression for the amplitude of the frequency response of the circuit in Figure 2. Your response will be a function of frequency $?$, as well as $R$ and $L$. Determine the low-frequency $(?=0)$ gain, high frequency $(???)$ gain, and the frequency at which the gain $20{\log }_{10}\left(?V_o?/?V_i?\right)=20{\log }_{10}(1/\sqrt{2})=?3\mathrm{dB}$ (also called the half power point, corner frequency, break frequency, $3dB$ frequency or cutoff frequency).
