EFFECT OF TRANSIENT AND FREQUENCY RESPONSE ON RC AND RLC CIRCUITS TO INSTANTANEOUS FORCING FUNCTION

Abstract

This study examines the effect transient and frequency response on RC and RLC circuits to Instantaneous forcing functions. The governing equations of electrical vibration for both circuits were formulated using Kirchhoff’s voltage law. The Laplace transform method was employed to find the transfer functions of both circuits giving solutions as frequency response and transient response respectively. It was observed that for transient response of both RC and RLC circuits, a voltage surge occurs immediately after t=0 and this phenomenon repeats after every second. While for the frequency response of both circuits, it was observed that for low-pass voltage, frequencies lower than 2000Hz are required and for high-pass voltage, frequencies higher than 104Hzare needed for optimal functionality.
