It has been over a decade since the Chinese publication of Line Loss in Electric Power Systems. To keep pace with technological developments, I started a revision as early as 2002, following the main principles that the theoretical framework and characteristics of the first edition should be retained, with new contents added according to new problems after the reform of electric power systems and the new requirements for line loss management practices and in combination with practical experience.

该论文讨论如何采用一种串行无逆的Berlekamp-Massey(BM)算法,设计应用于DVB系统中的RS(204,188)信道编码/解码电路,并通过FPGA的验证.RS解码器的设计采用无逆BM算法,并利用串行方式来实现,不仅避免了求逆运算,而且只需用3个有限域乘法器就可以实现,大大的降低了硬件实现的复杂度,并且因为在硬件实现上,采用了3级流水线(pipe-line)的处理结构.RS编码器的设计中,利用有限域常数乘法器的特性对编码电路进行优化.这些技术的采用大大的提高了RS编/解码器的效率,节省了RS编/解码器所占用资源.

General Description The LM621 is a bipolar IC designed for commutation of brushless DC motors. The part is compatible with both three- and four-phase motors. It can directly drive the power switching devices used to drive the motor. The LM621 provides an adjustable dead-time circuit to eliminate ``shootthrough'' current spiking in the power switching circuitry. Operation is from a 5V supply, but output swings of up to 40V are accommodated. The part is packaged in an 18-pin, dual-in-line package.

FEATURES Unique 1-Wire interface requires only one port pin for communication Multidrop capability simplifies distributed temperature sensing applications Requires no external components Can be powered from data line. Power supply range is 3.0V to 5.5V Zero standby power required Measures temperatures from -55°C to +125°C. Fahrenheit equivalent is -67°F to +257°F ±0.5°C accuracy from -10°C to +85°C Thermometer resolution is programmable from 9 to 12 bits Converts 12-bit temperature to digital word in 750 ms (max.) User-definable, nonvolatile temperature alarm settings Alarm search command identifies and addresses devices whose temperature is outside of programmed limits (temperature alarm condition) Applications include thermostatic controls, industrial systems, consumer products, thermometers, or any thermally sensitive system
