Ⅰ. Introduction
Ⅰ-1. Motive and Purpose
-Ubiquitous Trend of RFID (Radio Frequency Identification) can replace the barcode system. So it has emerged as a major area of ubiquitous and has been being utilized in many uses due to the high efficiency and several benefits. So our team wants to analyze and get a deep understanding about general RFID system through existed case studies.

Ⅰ. 서론
Pulse Oximeter(PO)는 혈액내의 산소포화도를 측정하는 것으로써 이는 총 헤모글로빈의 농도에 대해 산소를 포함하고 있는 헤모글로빈 농도의 비율로서 정의되어지는데, 이러한 비관혈적인 방법은 혈액의 채취나 카테터의 삽입 없이 혈액내의 산소 포화도를 측정함으로써 환자에게 고통을 주지
is harmful to human health in its own right.
2. NOx reaction produces tropospheric ozone.
3. NOx causes acid rain, smog, and destruction of forests.
- This problems become more serious due to the rapid increase of car.
Sensitivity
▪ Temperature
▪ Catalyst
▪ Large surface area
▪ Low carrier concentration
▪ Small grain size
▪ Metal oxide structure
modulation carrier are minimized since
even small phase errors can result in serious distortion of the demodulated message waveform.
⇒ ⇒
※ Coherent demodulation : If is time varying in an unknown and unpredictable manner,
the effect of the phase error can be serious distortion of the demodulated output
An AM signal can be demodulated using the same coherent demodulation techn
