1. Purpose
- In this experiment, we try to design simple FIR filters using A/D, D/A converter on the COMPACT51 board which is based on the 8051 microcontroller. Actually, the 8051 microcontroller is not proper to design an accurate high-order FIR filter owing to the 8051’s low complexity and performance. For this reason, the focus of this experiment is a design compromise between the performance and complexity based on the provided hardware.
- As in the previous experiment, you are recommended to try various attempts to design your own digital system rather than simply following the given procedure in the experiment handout.
2. Problem statement
- Design FIR filters (LPF, BPF, HPF) using A/D, D/A converter on the COMPACT51 board which is based on the 8051 micro-controller.
3. Pre-report (예비보고서에서 다루었으므로 생략하겠습니다.)
- Investigate various windows of FIR filter
Enumerate available windows.
Describe characteristic of each window.
Discuss which window is proper to this experiment.
4. Experimental procedure
1. Low Pass Filter
(1) FIR filter order selection
First, select the order of FIR filters. The order of FIR filter strongly affects processing time and, therefore, signal sampling rate.
먼저 여러 order에 대하여 sampling rate를 알아보았다.
