Description: This application report discusses the design of non-invasive optical plethysmography
also called as pulsoximeter using the MSP430FG437 Microcontroller (MCU). The
pulsoximeter consists of a peripheral probe combined with the MCU displaying the
oxygen saturation and pulse rate on a LCD glass. The same sensor is used for both
heart-rate detection and pulsoximetering in this application. The probe is placed on a
peripheral point of the body such as a finger tip, ear lobe or the nose. The probe
includes two light emitting diodes (LEDs), one in the visible red spectrum (660nm) and
the other in the infrared spectrum (940nm). The percentage of oxygen in the body is
worked by measuring the intensity from each frequency of light after it transmits
through the body and then calculating the ratio between these two intensities.

Description: 脉冲编码调制（PCM，Pulse Code Modulation）是一种将模拟语音信号转换成数字信号的编码方式，从数学上来看，量化过程就是把一个连续幅度值的无限数集合映射成一个离散幅度值的有限数集合，编码就是用一组二进制数来表示这些映射后的有限数。
国际标准化的PCM采用折叠二进制码，符合长途电话质量。根据量化方法的不同，PCM 可分为均匀量化PCM 和对数PCM 两大类，对数PCM中，A律和μ律编码都已被定为国际标准。
本程序实现了A律、μ律以及均匀量化三种PCM，并带有GUI界面，方便使用。可以计算编码后的码率、运行时间以及最小均方误差。-Pulse Code Modulation (PCM, Pulse Code Modulation) is an analog voice signal into digital signal encoding, from the mathematical point of view, the process is to quantify the magnitude of the value of an infinite number of continuous mapping into a discrete set of the limited range of values number set, code is a set of binary digits, said after a limited number of these maps.
By folding the International Standardization of PCM binary code, in line with long-distance telephone quality. According to the different quantitative methods, PCM can be divided into uniform quantization PCM PCM and the number of two categories, on the number of PCM, A law and μ-law code have been designated as international standards.
A law implemented in this program, μ law and the uniform quantization of three PCM, with a GUI interface, easy to use. Encoded bit rate can be calculated, running time and minimum mean square error.
