Part C
Consider the RLC band reject filter in (Figure 1). The quality factor of
the filter is \frac{2}{3}, the center frequency is 4 krad/s, and C = 80 nF. The
input to the filter is 125 cos \omega t V
Find the voltage drop $v_R(t)$ across the resistor when $\omega = \omega_0$. Suppose that $v_R(t) = A_R \cos(\omega t + \phi)$, where $A_R > 0$ and $-180^\circ < \phi \le 180^\circ$. Determine the
values of $A_R$, $\omega$, and $\phi$.
Express your answers using three significant figures separated by commas. Express $A_R$ in volts, $\omega$ in kiloradians per second, and $\phi$ in degrees.

Part D
Find the voltage drop $v_R(t)$ across the resistor when $\omega = 0.125\omega_0$. Suppose that $v_R(t) = A_R \cos(\omega t + \phi)$, where $A_R > 0$ and $-180^\circ < \phi \le 180^\circ$. Determine
the values of $A_R$, $\omega$, and $\phi$.
