Study of Passive Filters
Study of passive filter characterization for PCB application
Chapter 1: Introduction Project Description Passive filters are relatively simple electronic part that consists with resistors, capacitors, and inductors. The function of the passive filter is to allow a certain range of frequencies to pass, can be used to separate signals, passing those of interest, and also can reject noise and attenuating the unwanted frequencies. In this project, there are three type of passive filters that will be built on printed circuit board (PCB), to investigate the different result when applied as real circuit with the software design simulate as in theory. There are low pass filter, high pass filter and band pass filter. The design would be in second order Butterworth low pass, high pass and band pass filter using pi section/parallel at the first branch, with varies corner frequency from 1 kHz to 1 MHz (1 KHz, 10 KHz, 50 KHz, 100 KHz, 500 KHz, 1 MHZ). In addition, different types of PCB will be used to study the effects of different PCB characteristic on filters response.
Objectives
The objectives of these projects are: To study the passive filter characteristic with more detail. To design passive filter circuit using software and PCB application. To investigate the different result when applied as real circuit.
Resources and limitations There are some limitations for this project. Firstly, the design of the passive filter circuit using of electronic part that are not exactly as the calculated value in theory. To find the part will taking time and more cost.
Chapter 2: Literature Review
2.1 Introduction
For the few past years, there are several works and researches that have been done by researchers all over the world regarding the passive filter. In this chapter, some previous studies on passive filter will review.
2.2 Literature review
