Description: ：提出了一种单总线上多个数字温度传感器DS18B20的自动识别方法。通过设计由译码器74LS138、二输入四
与非门74LSOOP、模拟开关CD4066组成的电路，同时应用Keil C51工具编写DS18B20数字温度传感器软件程序，在单片
机的控制下，系统以开机初始化形式获取并保存所有传感器的序列号，自动识别传感器并进行多点测温。实验结果表明，
系统能将获得的序列号与各传感器对应起来，使传感器可即装即用，实现了真正意义上的自动识别。-A method of the automatic identification of multiple DS18B20 digital thermometers on a 1一W ire bus has been offered
by designing a circuit composed of a 74LS138 decoder，two 74LS00P quad 2-input NAND gates and two CIM066 quad bilateral
switchs，and writing programs using Keil C51 for accessing these DS18B20s．Under the control of SCM ，the system reads and
stores all DS18B20s’ROM codes in the form of initialization after the system is powered on，and then identifies the thermometers
automatically and measures the muthi—point temperature．The experiment result shows a one—to—one correspondence between the
DS18B20s’ROM codes is read and the temperature measuring points，which enables the therm ometers’plug and play．So the sys—
tern realizes the automatic identification in the real sens

Description: EDGE, the fastest transmission standard currently in use in GSM networks, is creating brand new opportunities for computing applications.
The MC75 from Siemens enables you to make use of this speed in your own products, facilitating multimedia downloads and data
streaming, for example.
EDGE, which stands for “Enhanced Data rates for GSM Evolution” is both a supplement and an alternative to UMTS. By employing this
standard, your products will be able to transmit data at very high speed, even in regions where UMTS is not available. In addition, due
to the Quad-Band technology, the module can be used in every GSM network worldwide. The MC75 includes an RIL driver, which makes
it particularly attractive for Microsoft © Windows Mobile™ based devices like smartphones and PDAs. The integrated USB port also
allows the use of the MC75 in applications like GSM/GPRS modems.-EDGE, the fastest transmission standard currently in use in GSM networks, is creating brand new opportunities for computing applications.

Description: Subroutine for continuous cross spectrum analysis of two
one-dimensional series x(i) and y(i) (i=1,...,n).
Input parameters and arrays: n,m, x(n), y(n),
n: number of data
m: biggest lag time length. Generally, m is between n/3 and n/10.
x(n),y(n): raw series
Output variables:
ol(0:m): frequency array
tl(0:m): periodic array
px(0:m): power spectrum of x(n)
py(0:m): power spectrum of y(n)
pxy(0:m): co-spectrum between x and y
qxy(0:m): quad-spectrum between x and y
rxy(0:m): coherence spectrum between x and y (it is between 0 and 1)
cxy(0:m): phase difference spectrum between x and y
If cxy(i)>0, then x trails y for the wave i, i.e. y leads x.
lxy(0:m): lag length spectrum between x and y
rxy951(0:m): 95 F-test confidence upper limit for coherence spectrum rxy
rxy952(0:m): 95 Goodman-test confidence upper limit for coherence spectrum rxy - By Dr. Li Jianping, September 6, 2001.
