Question

The RC circuit shown in the figure is

• A. a low - pass filter
• B. a high-pass filter
• C. a band-pass filter
• D. a band-reject filter

Answer 1

The correct option is C a band-pass filter

At $\omega \to \infty ,$Capacitor$\to$ short circuit
Circuit looks like,


$\frac{V_c}{V_1}=0$

At $\omega \to 0$,Capacitor$\to$ open circuit
Circuit looks like


$\frac{V_0}{V_i}=0$

So freqency response of the circuit will be.

So the circuit is Band - pass filter.
