## RLC Filter Analysis

Referring now to Fig.E.2, let's perform an*impedance analysis*of that RLC network.

### Driving Point Impedance

By inspection, we can write*parallel combination*of impedances and is given by the product divided by the sum of the impedances.

### Transfer Function

The transfer function in this example can similarly be found using voltage divider rule:### Poles and Zeros

From the quadratic formula, the two poles are located at### Impulse Response

The impulse response is again the inverse Laplace transform of the transfer function. Expanding into a sum of complex one-pole sections,**Next Section:**
