For the filter circuit shown in Figure P5.53:
a. Determine if this is a low-pass, high-pass, bandpass, or bandstop filter.
b. Determine the frequency response $\mathbf{V}_o(j \omega) / \mathbf{V}_{\mathrm{i}}(j \omega)$ assuming $L=10 \mathrm{mH}, C= 1 \mathrm{nF}, R_1=50 \Omega, R_2=2.5 \mathrm{k} \Omega$
