Chapter 2, Problem 2.19QAP

Interpretation Introduction

Interpretation:

The plot of the frequency response curve for low-pass RC filter is to be stated.

Concept introduction:

The RC filter or the RC circuit is the electrical circuit containing the resistor, capacitor and the voltage source.

The ratio of peak voltages at output to the input is define as $\frac{{\left(V_{\text{p}}\right)}_{\text{o}}}{{\left(V_{\text{p}}\right)}_{\text{i}}}=\frac{1}{\sqrt{{\left(2\pi fRC\right)}^2+1}}$, where $f$ is the frequency, $R$ is the resistance of the resistor and $C$ is the capacitance of the capacitor.
