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.

該論文討論如何采用一種串行無逆的Berlekamp-Massey(BM)算法,設計應用于DVB系統中的RS(204,188)信道編碼/解碼電路,并通過FPGA的驗證.RS解碼器的設計采用無逆BM算法,并利用串行方式來實現,不僅避免了求逆運算,而且只需用3個有限域乘法器就可以實現,大大的降低了硬件實現的復雜度,并且因為在硬件實現上,采用了3級流水線(pipe-line)的處理結構.RS編碼器的設計中,利用有限域常數乘法器的特性對編碼電路進行優化.這些技術的采用大大的提高了RS編/解碼器的效率,節省了RS編/解碼器所占用資源.

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
